Grade 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application.

321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600°F temperature range. For service temperatures up to about 1600°F, a stabilizing treatment at 1550-1650°F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.

<strong>2036 aluminum</strong> this is an early application of a kind of hard aluminum, commonly known as standard hard aluminum, with moderate strength, annealing, quenching and hot state plasticity is good, heat treatment can be strengthened, quenching and natural aging state in use, spot welding weldability is good. <br> <strong>2036 aluminum alloy</strong> features: high strength, a certain heat resistance, can be used for working parts below 150℃.<br> <strong>The strength</strong> of 2036 alloy is higher than that of 7075 alloy.

<strong>1100 aluminum alloy</strong> is 99.0% ordinary industrial pure aluminum. <br> <strong>Heat treatment </strong>can not be strengthened; Low strength, but good ductility, formability, weldability and corrosion resistance;<br> <strong> After anodic oxidation,</strong> the corrosion resistance can be further improved and a beautiful surface can be obtained.
