This paper deals with the problems such as extrusion failure and cxtrusion breaksocurring during the extrusion of silver-graphite materials at high cxtrusion ratio (so called fibretype extrusion).
本文分析了银石墨触头材料在大挤压比的纤维化挤压中，出现的挤压力过大引起闷车和挤压碎裂的问题。

These are graphite, high silicon cast iron, lead silver alloy, platinum, and even scrap steel rails.
所用材料有石墨、高硅铸铁、铅银合金、铂、甚至废钢轨等。
