Aluminum alloy hand board is one of the industrial hand boards. Let‘s take a look at its composition and use. Aluminum alloy is a general term for aluminum-based alloys. The primary alloying elements are copper, silicon, magnesium, zinc, and manganese, and the non-essential alloying elements are nickel, iron, titanium, chromium, and lithium. Aluminum alloy has low density, but relatively high strength. It is close to or better than high-quality steel. It has good plasticity and can be processed into various profiles. It has electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and is second only to steel.
