Main features and uses of various grades of aluminum alloys

ZL101 is characterized by simple composition, easy smelting and casting, good casting performance, good air tightness, good welding and cutting performance, but not high mechanical properties. It is suitable for casting thin-walled, large-area and complex-shaped parts with low strength requirements, such as pump casings, gear boxes, instrument casings (frames) and zeroes on home appliances. Sand casting and gravity casting are mainly used.

Since ZL101A is based on ZL101 with a trace amount of Ti added,  Cast Engine Oil Pump Cover the grains are refined and the structure of the alloy is strengthened. Its comprehensive performance is higher than that of ZL101 and ZL102, and it has better corrosion resistance. Structural parts and high-quality aluminum castings for various structural parts on motorcycles, automobiles, home appliances, and instrumentation products. Sand casting and aluminum alloy gravity casting are mostly used. ZL114A is a complex alloyed alloy. Due to the addition of Mn and Ti, the alloy has excellent casting properties, good corrosion resistance, air tightness and high strength.

Its welding and machining performance is average. It is suitable for casting dynamic structural parts with complex shapes and heavy loads (such as structural parts of aircraft engines, water pumps, oil pumps, impellers, etc.), and parts that require good air tightness and work at higher temperatures. Gravity casting and low pressure casting are mainly used.
