5.FAQ

1.Q: What about leadtime ?
   A: Normally the leadtime is 60days after we receive the deposit and confirm the details. All the press machines we use is the best quality in China Yangli brand. The press machine leadtime from Yangli is 50days, the best leadtime we can give is 60days.

2.Q: What's the lead time for moulds?
   A: Normally the mould leadtime is 45 days after we confirm all the details with customer. Our professional mechanical enginners from Austria will design the mould according to the samples from customer, or by the specifications offered by customers.

3.Q:What kinds of mould you can make? and what is your strong point for the moulds?
   A: we can make wrinkle wall mould and smooth wall mould both. For wrinkle wall mould we can make, 79" pan, fish pan, bbq pan. For smooth wall mould we can make muffin cup, and cake cup, tar cup,etc. We can also make 2 or 3 portion conatiner moulds as long as you offer us sample or specifications. Our strong points are all our moulds are WEDMLS cut, which makes the mould more accurate and precise. Important materials likestainless steel parts we make in Austria. We also recut after heat treatment, which most of makers do not take this process..

Q:How does the formability of aluminum sheet vary with different alloys?: Variations in chemical composition and mechanical properties result in significant differences in the formability of aluminum sheet among different alloys. To enhance specific characteristics like strength, corrosion resistance, and formability, aluminum alloys are typically combined with elements such as copper, manganese, magnesium, and zinc. Aluminum alloys like the 1xxx series (pure aluminum) and the 3xxx series (manganese alloyed) are highly formable and commonly used for deep drawing applications. These alloys can be shaped into complex forms without cracking or tearing. In contrast, alloys with higher strength properties, such as the 2xxx series (copper alloyed) and the 7xxx series (zinc alloyed), generally have reduced formability. Although these alloys are often used in structural applications where strength is crucial, they require careful handling and processing to avoid defects during forming. Alloys in the 5xxx series (magnesium alloyed) offer a good balance of formability and strength. They are widely used in industries like automotive and aerospace, as they can be easily formed into different shapes while providing sufficient strength and corrosion resistance. It's important to note that the formability of aluminum sheet is not solely determined by the alloy composition. Other factors such as sheet thickness, forming temperature, and the specific forming process employed (e.g., deep drawing, bending, stretching) also influence formability. These factors interact with alloy properties to affect the formability characteristics of aluminum sheet. Therefore, careful selection of the appropriate alloy and process parameters is essential to achieve the desired formability for specific applications.

Q:What are the standard sizes and availability of aluminum sheets in the market?: The standard sizes and availability of aluminum sheets in the market can vary depending on the location and specific requirements. However, there are some commonly available sizes that can generally be found in most markets. In terms of thickness, aluminum sheets are commonly available in 0.02 to 0.2 inches (0.5 to 5 millimeters) thickness range. Thinner sheets (0.02 to 0.06 inches) are often used for lightweight applications such as signage or crafts, while thicker sheets (0.1 to 0.2 inches) are typically used for more heavy-duty applications like construction or industrial purposes. Regarding width and length, standard aluminum sheet sizes are often offered in 4 feet by 8 feet (48 inches by 96 inches) or 4 feet by 12 feet (48 inches by 144 inches). These dimensions are widely available and suitable for various applications. However, it's important to note that custom sizes can also be ordered or cut from larger sheets to meet specific project requirements. Availability of aluminum sheets can be found in various locations, including local hardware stores, metal suppliers, and online marketplaces. It is always recommended to check with local suppliers or conduct online research to determine the specific sizes and availability in your area. Additionally, different grades or alloys of aluminum may have varying availability, so it's essential to consider the specific requirements of your project when sourcing aluminum sheets.

Q:why can't aluminum sheet burn after polishing?: because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.

Q:Could copper wire be welded with aluminum sheet?: Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.

Q:What is the typical modulus of elasticity of aluminum sheets?: The modulus of elasticity of aluminum sheets typically varies based on the alloy and temper. Nevertheless, an often utilized figure is approximately 70 GPa (gigapascals) or 10 million psi (pounds per square inch). This figure denotes the material's stiffness or rigidity, revealing its capacity to endure deformation when subjected to stress. It is essential to acknowledge that diverse grades and conditions of aluminum might possess slightly distinct modulus of elasticity values. Hence, consulting the specific material specifications is advisable for precise information.

Q:Can aluminum sheet be used for heat shielding?: Yes, aluminum sheet can be used for heat shielding. Aluminum has a high thermal conductivity and excellent heat dissipation properties, making it an effective material for heat shielding applications. Its ability to reflect radiant heat also makes it suitable for use in thermal barriers and insulation systems. Additionally, aluminum sheet is lightweight, corrosion-resistant, and easily fabricated, making it a cost-effective choice for heat shielding in various industries such as aerospace, automotive, and electronics.

Q:Also what are some intersting facts about Aluminum? (the element) thanks 2 any 1 who answers =): Corrosion resistance due to passivation and low density.

Q:Can aluminum sheets be used in construction?: Construction can indeed utilize aluminum sheets. Aluminum, a versatile and lightweight material, possesses numerous advantageous properties for construction purposes. Its corrosion resistance allows for both indoor and outdoor applications. Moreover, aluminum sheets exhibit a high strength-to-weight ratio, granting them durability and strength while remaining relatively lightweight. This characteristic proves advantageous in construction projects where weight is a consideration. Furthermore, aluminum is non-toxic and highly recyclable, making it an environmentally conscious option. When combined with its aesthetic appeal and ease of fabrication, aluminum sheets become a favored choice for a variety of construction applications such as roofing, cladding, wall panels, window frames, and more.

Q:Are 101 aluminum sheets suitable for architectural louvers or sunscreens?: Yes, 101 aluminum sheets are suitable for architectural louvers or sunscreens. They possess excellent strength, durability, and corrosion resistance, making them ideal for outdoor applications. Additionally, their lightweight nature allows for easy installation and maintenance.
