The world of screws - Materials

There are many kinds of screws, which can be divided by appearance, material, industry, standard, process and so on. In the last issue, we introduced some products classified by appearance. In this issue, we will have a general understanding of the materials commonly used in screws.

Generally, screws are made of carbon steel (iron), stainless steel, aluminum and aluminum alloy, titanium and titanium alloy, copper and copper alloy and other metal materials. In my opinion, titanium alloy is a popular product for high-performance mountain bikes and airplanes. Shouldn't it be made of copper? Once you take it, it's super light. After class, I know that this is the appearance of titanium alloy screws after electroplated gold!
