英国AE公司最近研究出一种新的高强度活塞合金材料──AExelsius135，据称这种新材料的高温强度比目前使用的活塞合金提高了25％～30％。这种材料为含St13％和C。。5％的高纯度铝合金。AE公司称此材料的高温强度可以满足开发具有锐线燃烧室的汽车柴油机活塞的需要，以达到降低 British AE recently developed a new high-strength piston alloy material, Axexius135, which is said to increase the high-temperature strength of the new material by 25% to 30% over currently used piston alloys. This material contains St13% and C. . 5% high purity aluminum alloy. AE said the high temperature strength of the material meets the need to develop a piston for a car diesel engine with a sharp-edged combustion chamber to reduce
