用于汽车、飞机、电子设备机械等的铝合金锻造件,有效地利用了高材料强度比的优点。并且作为新材料之一,发展了高强度、高耐磨的铝复合材料。因此,铝合金的使用范围与日俱增。这些铝合金热、冷锻造制件,既要与压铸件、铸造件和挤压件等竞争,还要以满足更高强度要求为中心的技术开发。由于铝合金的塑性流动性大,要求锻件形状达到接近零件的最后形状,因而形状往往很复杂。这样,模具材料的耐压缩强度、韧性等就要求具有与锻造钢铁的锻模相似的高性能。
Aluminum forgings for automobiles, airplanes, electronic equipment and machinery, etc., effectively take advantage of the high material strength ratio. And as one of the new materials, the development of high strength, high wear-resistant aluminum composite materials. Therefore, the use of aluminum is increasing. These aluminum alloy hot and cold forged parts, both with the die casting, casting and extrusion competition, but also to meet the higher strength requirements as the center of technology development. Due to the high plasticity of the aluminum alloy, the shape of the forging needs to be close to the final shape of the part, so the shape is often complicated. In this way, the mold material’s compressive strength, toughness, etc., require high performance similar to that of forged steel.
