FAQ

I get to do an aluminum blank for a fence and I am curious whether I can put slots in it with the router?I am not sure how thick it is, may say 3/16's.

Yes you can use a router on aluminium. Use some kind of a fence, a piece of angle iron or a block of hardwood. Use a new bit, an old dull one will cause you problems. Pre-drill smaller holes than the slot width at each end of the slot. Stay back away from the end of the slot about 1/32 of an inch. Make several passes, at a depth of about 1/16 of an inch, per pass. If you can, make the slot with a bit smaller than the finished slot width. Use a 3/16 bit for a 1/4 inch slot. Use a 5/16 bit for a 3/8 inch slot. This will give cleaner slot edges and allow you to accurately make the slot width that you want. You can do this dry, but a little WD-40 oil will give even cleaner slot edges. Also climb mill the last pass on each slot edge to give a better/ smother edge. Climb Milling is pushing the router backwards of the way you normally travel in wood. Ben

Aluminum sheets are indeed a fitting choice for HVAC systems. The popularity of aluminum in HVAC systems stems from its numerous advantageous properties. To begin, aluminum is both lightweight and robust, making it effortless to handle and install in HVAC systems. Its low density also enables cost-effective transportation and reduces the overall weight of the HVAC units. Furthermore, aluminum possesses exceptional resistance to corrosion. Given that HVAC systems often encounter moisture and condensation, particularly in air conditioning units, aluminum's corrosion resistance ensures its durability and longevity in such environments. Moreover, aluminum sheets exhibit commendable thermal conductivity, facilitating efficient heat transfer throughout the HVAC system. This property holds particular significance in heating and cooling applications, as it aids in effectively distributing the desired temperature. In addition, aluminum is a non-toxic material, rendering it safe for use in HVAC systems that circulate air within buildings. It does not emit any harmful particles or gases, thereby ensuring the quality of indoor air. Lastly, aluminum is highly recyclable, contributing to its environmental friendliness. The ability to recycle aluminum sheets reduces the carbon footprint associated with HVAC systems and aligns with sustainability objectives. Taking all these advantages into account, aluminum sheets undeniably prove suitable for use in HVAC systems. They offer an optimal combination of strength, corrosion resistance, thermal conductivity, safety, and environmental friendliness.

Aluminum wiring can be a fire hazard because it can oxidize, or combine with oxygen..

Well, aluminum oxide is Al2O3, right? So for every 2 aluminum atoms there are 3 oxygen atoms, So, if you have three moles of aluminum, you'll need 4 and a half moles of oxygen to react completely with the aluminum. One mole of oxygen atoms weighs 16 grams, so 4.5 moles weighs 72 grams, right? Now it could be that your teacher told you three point zero zero moles of aluminum to get you to use two significant figures, so if you've studied significant figures you may want to look up a more accurate number for the atomic weight of aluminum, and carry the calculation through to three significant figures. Otherwise, 72 is a fine answer.

There are several methods for perforating aluminum sheets, including laser cutting, punching, drilling, and waterjet cutting. Each method has its own advantages and is chosen based on factors such as desired hole size, shape, precision, and production volume.

Yes, aluminum sheets are suitable for manufacturing heat exchanger tubes. Aluminum has excellent thermal conductivity, corrosion resistance, and is lightweight, making it an ideal material for heat transfer applications.

Yes, aluminum sheets can be used for manufacturing electronic heat sinks due to their excellent thermal conductivity and lightweight properties, making them effective in dissipating heat from electronic components.

Aluminum sheets are indeed appropriate for cladding purposes. The utilization of aluminum as a cladding material is widely favored due to its numerous benefits. Firstly, its lightweight nature facilitates easier handling and installation. This leads to a reduction in the overall weight of the cladding system and a minimization of structural loading. Secondly, aluminum showcases exceptional durability and resistance to corrosion, rendering it suitable for both interior and exterior applications. Additionally, it possesses weather-resistant qualities, ensuring that the cladding remains in optimal condition even in harsh climates. Furthermore, aluminum is an incredibly versatile material that can be effortlessly shaped and fabricated, thus allowing for a diverse range of design options. It may be painted or coated with various finishes to enhance its appearance and provide additional protection. Moreover, aluminum cladding necessitates minimal maintenance, as it does not require frequent cleaning or painting. In summary, aluminum sheets are an exceptional choice for cladding due to their lightweight nature, durability, versatility, and low maintenance requirements.

I have a problem when machining aluminium in my machine shop. There are times when the machines aluminium surface turns yellowish (somtimes brown). I do not know what is the main cause of the problem. Is it due to the coolant used?

Aluminum oxides may appear in different colors depending on hydration states and other variables. Look in a CRC Handbook of Chemistry Physics if available for aluminum compounds and their colors. The colors that you see may also have as much to do with the surface finish as the color of the material on the surface. A microscopically rough surface will appear dark next to a polished surface due to light scattering. I will agree with Ling in principle, but not on details. EDS detection limits on homogeneous samples can be better than 0.1%, although not so good for elements at the light end of the detection range. Current detectors can detect chlorine (a common culprit for aluminum discoloration) at about 0.1%. Your problem with detection and one that Ling has addressed previously may be that a thin film of contamination would not be easily detected by EDS. As Ling suggests, SIMS is a good technique for detecting thin films and low concentrations. The problem with SIMS in this case may be that the detection limits are too good and the technique cannot be quantified. SIMS would detect 2 ppm of chloride and you couldn't tell for sure whether it was 2 ppm, which is probably not an issue here, or 2000 ppm, which would be significant. I would suggest x-ray photoelectron spectroscopy (ESCA or XPS) as an alternative for further study. The technique will analyze thin films (20 A) and detection limits are good enough (about 0.1%). In addition, XPS will give you information about the compounds present, e.g. whether the oxygen is aluminum oxide, aluminum hydroxide, etc. Good Luck.
