Aluminum alloy composite precision investment casting accessories

Ningbo Suijin has strong abilities casting stainless steel, aluminum, carbon steel, brass, bronze, cobalt, and many other steels, is committed to delivering the highest quality stainless steel investment castings. We has the capability of producing aluminum alloy investment castings with an exceptional surface finish and fine detail.

The composite casting process can be combined with materials with different properties to give play to their respective advantages and meet the requirements for the use of spare parts. Metallurgical spare parts are subject to impact and wear under high temperature environments, and are generally made of heat-resistant steel materials or wear-resistant materials, but the same metal material is often difficult At the same time bear the effects of high temperature and wear. Ordinary cast steel materials have good strength and toughness, but wear resistance and heat resistance are poor, which is difficult to meet the requirements; if the high alloy material is cast as a whole, the process and technical performance is poor, which is easy to produce defects, and the yield rate Too low, and the cost of high-alloy materials is too high. The method of casting surface alloying can not only ensure that the core has good strength and toughness, but also meet the special properties required by the surface. Combined with the advanced lost foam casting process, it is suitable The surface alloying process to improve wear resistance and heat resistance. It improves the problems of pores and slag inclusion between the alloying layer and the bonding part of the body. The placement of the alloyed powder (paste block) is simple and reliable. The matrix used is Ordinary cast steel, the alloy layer is a high-Cr alloy, and alloy materials containing Mo, Ni and WC are added at the same time. The metallurgical bond between the alloyed layer and the matrix is ​​achieved, and the obtained alloyed layer containing high Cr, W and other elements, alloy The surface of the layer is flat, the composition of the cross section within a certain thickness of the alloy layer, the hardness is relatively uniform, and it has good wear resistance and heat resistance. The obtained casting surface alloyed composite layer has obvious wear resistance and oxidation resistance than the body material Performance, the wear resistance of the alloyed layer is 3 to 5 times that of the body cast steel ZG70 comparison sample, and the oxidation resistance is about 50% higher than that of the body sample.
