FAQ

What gas is best for welding aluminum strip?
If the welded aluminum strip is welded by argon arc welding, it is best to use high purity argon and 5 purity of 9.
How to use batteries, magnets, cans of aluminum belt to make a rotating aluminum belt device, please explain
Attract aluminum cans with magnets to make them turn It seems impossible, and we know that magnets can only attract iron, cobalt, nickel and their alloys, and will not attract aluminum products. But the device we built below successfully realized this impossible function.
1060 what is the hardness of aluminum strip?
Brinell hardness measurement method is to use a hardened steel ball, such as the diameter of 5 mm steel ball, with a certain force into the parts or material surface, and then measure the indentation size, read the hardness value.
Can welding of aluminum with water-cooled DC hydrogen arc welding machine how much money
If the 380V is about 4500 or so, if it is pure industrial machine more than 10 thousand. This, you can go to see the semi industrial uses of 380V Classic DC argon arc welder with special industrial grade Wei Odin WSME315B inverter pulse argon arc welding of aluminum AC argon arc welding machine is a machine with three".
Aluminum band treble sounds good?
The impedance of the 1. aluminum band tweeter is almost constant, so there is an excellent frequency response curve in the high frequency band that does not begin to decay until near 40khz.2., compared to ordinary metal treble, sensitivity is higher, the aluminum ribbon tweeter sensitivity is almost above 90db.
How to distinguish between good and bad aluminum bands?
Compare the flexibility and strength of aluminium pinch plateThe differential method is simple: take a piece of aluminum buckle, with his hand he bent aluminum buckle not good will easily be bent, and will not return to its original shape, and good bending to aluminum buckle requires effort, and after bending, will rebound to a certain extent, the difference between the strength and toughness this is the aluminum. After the installation of a good aluminum pinch plate, there will be no bending or middle fall.
Which brand of aluminium band for dry transformer?
Personal feeling 1070 should be better, because a higher proportion of content, electrical conductivity must be better, but at present, the market is indeed everyone's use.
