The 7050 alloy is renowned for its incredibly robust composition, primarily strengthened by zinc as its main alloying element. This specific formulation gives these chequered plates their signature high strength, which is impressively maintained even in thick sections. They also possess excellent resistance to stress corrosion cracking, a critical feature for long-term structural integrity. Furthermore, these plates offer good toughness, making them less prone to fracture under impact. This powerful combination of mechanical properties makes the 7050 grade a standout choice where superior performance is non-negotiable.
