4032 round aluminum bar rod for forged piston

The 4032 aluminum rod is made of silicon as the main alloying element. The alloy is mainly used for the manufacture of aluminum alloy welding because of its high silicon content, low melting point, good melt flowability, easy shrinkage, and no brittleness in the final product. Additive materials such as brazing sheets, welding rods and welding wires. In addition, some of these alloys are also used to make pistons and heat-resistant parts because of their good wear resistance and high temperature performance.


 

4032 aluminum bar are mainly used for machining forged pistons, machinery manufacturing, transportation machinery, power machinery and aviation industry. Aircraft fuselage, skins, compressors, etc. are often made of aluminum alloy to reduce their own weight. The use of aluminum alloy instead of steel plate welding can reduce the structural weight by more than 50%.
