沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)所用(yong)的(de)(de)(de)(de)(de)材料(liao)與沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)工(gong)藝(yi)的(de)(de)(de)(de)(de)關系十(shi)分密(mi)切，它會直接影響到沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)工(gong)藝(yi)設計、沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)質量(liang)和產(chan)品使用(yong)壽命，甚(shen)至還會影響組織(zhi)均衡(heng)生(sheng)產(chan)和沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)生(sheng)產(chan)成(cheng)本。在選擇沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)材料(liao)時，首先要(yao)(yao)滿足制(zhi)件(jian)(jian)的(de)(de)(de)(de)(de)使用(yong)要(yao)(yao)求。一般來說(shuo)，對(dui)于機器上(shang)的(de)(de)(de)(de)(de)主(zhu)要(yao)(yao)沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)，材料(liao)要(yao)(yao)求具有較高(gao)的(de)(de)(de)(de)(de)強度(du)盒剛(gang)度(du)；點擊電器上(shang)的(de)(de)(de)(de)(de)某些沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)，要(yao)(yao)求有較高(gao)的(de)(de)(de)(de)(de)導電性和導磁性；汽車及飛機上(shang)的(de)(de)(de)(de)(de)沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)，要(yao)(yao)求有足夠的(de)(de)(de)(de)(de)強度(du)，盡可能要(yao)(yao)減輕質量(liang)；化工(gong)容器上(shang)的(de)(de)(de)(de)(de)沖(chong)(chong)(chong)(chong)壓(ya)(ya)(ya)件(jian)(jian)要(yao)(yao)求耐腐蝕性等。

所以(yi)不(bu)同的(de)(de)使用要(yao)求(qiu)就決定了應選用不(bu)同的(de)(de)沖(chong)壓(ya)材(cai)料。但(dan)從沖(chong)壓(ya)工藝(yi)上考慮，材(cai)料還應滿足沖(chong)壓(ya)工藝(yi)要(yao)求(qiu)，以(yi)保(bao)證沖(chong)壓(ya)過程能順利完成。
