Material: ironDensity: ≥ 7.6g/cm3Hardness: 40-45HRCTensile strength: 300mpaYield strength: ≥180mpaSurface treatment: vibrate grinding + bluingFeature：The shifting fork 's function is connection. To make this item, after sintering, we need to do heat treatment and nickel plate treatment.Advantage: Most advanced smart lock parts are made by MIM. Advanced smart lock requires high intensity. Thus, compared with traditional technology, using MIM to make this part can meet such requirement because MIM material density is high and the part hardness is much better than forge and powder metallurgy. Meanwhile, lock parts usually need to have wonderful surface. The surface for MIM parts is smooth enough to do any high demand surface treatment such as oxidation, galvanization, nickelage etc., so as to pass the salt spray test.MIM technology can make various kinds of metal parts. If your part is made of stainless steel, steel, iron and the shape is complex......url:http://www.no2-machinery.com
