TABLE 1–2 The thermal conductivity of an alloy is usually much lower than the thermal conductivity of either metal of which it isposed Pure metal or alloy Copper Nickel Constantan (55% Cu, 45% Ni) Copper Aluminum Commercial bronze (90% Cu, 10% Al) k, W/m·K, at 300 K 401 91 23 401 237 52 widespread use in the electronics industry.The strength of heat treatedmercial Al alloys exceeds 550 MPa. Aluminium and its alloys are used widely in aerospace, automotive, architectural, lithographic, packaging, electrical and electronic applications. It is the prime material of construction for the aircraft industry throughout most of its history.HM provides high-quality Master Alloys at apetitive price, which can be used in Scientific research or industrial production. tendency. The mechanical properties are not high, and the strength limit is 210～280MPa. Heeger Materials provides high-quality Magnesium Manganese Master Alloy in the shape of Waffle Ingot, rod, and shot at a Dec 17, 2019 · These listed alloys are frequently employed in the annealed condition (O temper) for general application, but when higher strength is needed, these alloys are employed in a strain-hardened condition (H temper) such as H 111, H 112, H116, and H32 [45, 46].
