材料对自由锻件锻压设备的适应性

自由锻件铝合金：锻造变形量很大时，优先选用水压机，否则可任选。

铍合金：优先选用水压机，因慢速下的可锻性良好。

铜合金：优先选用锤、螺旋压力机或曲柄压力机，但对变形速率敏感的青铜和高锌黄铜，应优先选用水压机。

铌合金：锤、螺旋压力机和曲柄压力机，当合金请求高温锻造时，优先选用水压机。

镁合金：因其快速变形的可锻性差，应优先选用水压机。

钼合金：当请求高温锻造时，优先选用锤、螺旋压力机或曲柄压力机。

镍基合金：根据锻件的截面厚度选定；锻造薄的截面（小于12. 7毫米）锻件时，优先选用锤、螺旋压力机、曲柄压力机，否则可任选。

碳钢和低合金钢：锻造含有薄的截面的锻件或氧化皮肃清较难题时，优先选用锤、 螺旋压力机或曲柄压力机，否则可任选。

不锈钢：含有薄截面的锻件，优先选用锤、螺旋压力机或曲柄压力机，否则可任选。

钽合金：高温锻造时，优先选用锤、螺旋压力机或曲柄压力机。

钛合金：含有薄截面的锻件，优先选用锤、螺旋压力机或曲柄压力机，否则可任选。

钨合金：高温锻造时，优先选用锤、螺旋压力机或曲柄压力机。

锆合金：当毛坯有包套时，优先选用水压机（高于760℃）；锻造温度低于 760℃的，可任选。

Adaptability of materials to free forging press equipment

Free forging aluminum alloy: When the forging deformation is large, the hydraulic press is preferred, otherwise it can be optional.

Niobium alloy: The hydraulic press is preferred because of the good forgeability at slow speed.

Copper alloy: Hammer, screw press or crank press are preferred, but bronze and high-zinc brass, which are sensitive to deformation rate, should be preferred.

Niobium alloys: hammers, screw presses and crank presses. When alloys are required for high temperature forging, hydraulic presses are preferred.

Magnesium alloy: Due to its poorly deformable forgeability, a hydraulic press should be preferred.

Molybdenum alloy: When high temperature forging is requested, hammer, screw press or crank press are preferred.

Nickel-based alloy: selected according to the section thickness of the forging; forging a thin section (less than 12.7 mm) forging, it is preferred to use a hammer, a screw press, or a crank press, otherwise it may be optional.

Carbon steel and low-alloy steel: When forging a forging or a scale with a thin section, it is preferable to use a hammer, a screw press or a crank press, otherwise it may be optional.

Stainless steel: Forgings with a thin section, preferably a hammer, screw press or crank press, otherwise optional.

Niobium alloy: For high temperature forging, hammer, screw press or crank press are preferred.

Titanium alloy: Forgings with a thin section, preferably a hammer, screw press or crank press, otherwise optional.

Tungsten alloy: For high temperature forging, hammer, screw press or crank press are preferred.

Zirconium alloy: When the blank has a wrap, the hydraulic press (above 760 ° C) is preferred; the forging temperature is lower than 760 ° C, optional.
