通过装罐粉末的挤压可以得到完全致密的、可以机械加工的AlnicoV和钛含量高达8%的AlnicoⅧ的棒材。钴或铁基主合金粉末同适当的元素粉末掺混、装罐和在相当低的温度进行挤压。适当地调整几个工艺参数,挤压材料的密度可接近理论值而硬度值Rc为17—30。可以容易地进行模锻、车削、铣削、钻孔和攻丝等 Extrusion of canned powders gives fully dense, mechanically machinable AlnicoV and Alnico VIII bars with a titanium content of up to 8%. Cobalt or iron-based master alloy powders are blended with the appropriate elemental powder, canned and extruded at relatively low temperatures. Proper adjustments to several process parameters, extrusion material density can be close to the theoretical value and the hardness value of Rc 17-30. Forging, turning, milling, drilling and tapping can be done easily
