Aluminium Ingot 99.7%

Al-si alloy, the mass fraction of Si is 4%~22%. Because al-Si alloy has excellent casting properties, such as good fluidity, good air tightness, small shrinkage and warm tendency, after metamorphic and heat treatment, it has good mechanical properties, physical properties, corrosion resistance and moderate machining performance. Is the most variety of cast aluminum alloy, the most widely used kind of alloy. The characteristics and application of common cast Al-Si alloy are as follows:

(1) ZL101(A) alloy ZL101 alloy has good air tightness, fluidity and thermal cracking resistance, has medium mechanical properties, welding performance and corrosion resistance, simple ingredients, easy to cast, suitable for A variety of casting methods. ZL101 alloy has been used to withstand medium load of complex parts, such as aircraft parts, instruments, instrument housing, engine parts, automotive and Marine parts, cylinder, pump body, brake drum and electrical parts. In addition, ZL101A alloy based on ZL101 alloy strictly control the impurity content, and through improving the casting technology to get higher mechanical properties of ZL101A alloy, has been used to cast a variety of shell parts, aircraft pump body, automobile gearbox, fuel tank elbow, aircraft accessories and other load bearing parts.

(2) ZL102 alloy ZL102 alloy has the best thermal cracking resistance and good air tightness, as well as good liquidity, can not be heat treatment strengthening, low tensile strength, suitable for casting large thin-walled complex parts, mainly suitable for die casting. This kind of alloy is mainly used to bear low-load thin wall casting with complex shape, such as various instrument casings, automobile casing, dental equipment, piston and so on.
