11-13.5% Silicon Content, Excellent Wear Resistance – 4032 Heat-Treatable Aluminum Alloy Round Bar

4032 aluminum alloy is a wrought aluminum alloy belonging to the 4000 series (Al-Si system), primarily alloyed with Silicon (Si) and Magnesium (Mg). Unlike common aluminum alloys, 4032 features a distinctive composition of 11.0-13.5% Silicon, along with strengthening elements like Copper (0.5-1.3%), Magnesium (0.8-1.3%), and Nickel (0.5-1.3%). This unique formulation delivers exceptional performance at elevated temperatures, characterized by low thermal expansion, high strength, and excellent wear resistance. It is the specialized material for forged pistons in internal combustion engines – the ideal choice for components enduring intense heat and pressure.
