首先我(wo)們先說下地(di)漏的特點(dian)，地(di)漏是(shi)(shi)五金(jin)件(jian)，主(zhu)體材(cai)(cai)料多以(yi)不銹鋼(gang)黃(huang)銅為主(zhu)，原因(yin)是(shi)(shi)地(di)漏是(shi)(shi)用在衛生間濕區，長期接觸(chu)污(wu)水，所以(yi)材(cai)(cai)質(zhi)選(xuan)擇中耐腐蝕和(he)抗氧化的304不銹鋼(gang)和(he)加上(shang)電鍍保護(hu)的黃(huang)銅，這兩(liang)種材(cai)(cai)質(zhi)無論從耐腐蝕，抗氧化，以(yi)及硬度，都比較(jiao)適合作為地(di)漏的主(zhu)體材(cai)(cai)料，但是(shi)(shi)市場上(shang)有很多廉(lian)價的201不銹鋼(gang)，銅合金(jin)產品，底價在銷售。
銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合(he)金(jin)和黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)地漏的(de)(de)(de)區(qu)別，解釋幾個名(ming)詞：純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，全(quan)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)和黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)區(qu)別：含(han)量(liang)為(wei)(wei)99.7～99.95%的(de)(de)(de)叫純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong),純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)富有(you)延展性(xing)(xing).象一滴(di)水那么大(da)小的(de)(de)(de)純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong),可拉成長(chang)達(da)(da)兩公(gong)里的(de)(de)(de)細絲,或壓(ya)延成比床還大(da)的(de)(de)(de)幾乎透明(ming)的(de)(de)(de)箔(bo),純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)最(zui)可貴(gui)的(de)(de)(de)性(xing)(xing)質(zhi)是導(dao)電(dian)(dian)性(xing)(xing)能,具有(you)超(chao)高(gao)的(de)(de)(de)導(dao)電(dian)(dian)率因此多用(yong)于電(dian)(dian)氣工業,純銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)不適合(he)做(zuo)衛浴(yu)制品,因為(wei)(wei)其硬度(du)(du)不夠.全(quan)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)為(wei)(wei)模糊(hu)的(de)(de)(de)概念,指(zhi)成分為(wei)(wei)"銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)"的(de)(de)(de)材質(zhi). 以鋅為(wei)(wei)主加(jia)(jia)元素(su)的(de)(de)(de)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合(he)金(jin)稱為(wei)(wei)黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong).鋅含(han)量(liang)在(zai)32%以下時,隨著含(han)鋅量(liang)的(de)(de)(de)增加(jia)(jia),黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)強(qiang)(qiang)度(du)(du)和塑(su)性(xing)(xing)不斷提高(gao),當含(han)鋅量(liang)達(da)(da)到30%-32%時,黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)塑(su)性(xing)(xing)最(zui)好(hao)(hao).當含(han)鋅量(liang)超(chao)過(guo)39%以后,強(qiang)(qiang)度(du)(du)繼續升高(gao),但(dan)塑(su)性(xing)(xing)迅速下降.當含(han)鋅量(liang)大(da)于45%以后,強(qiang)(qiang)度(du)(du)也開始急(ji)劇(ju)下降.我們(men)采用(yong)標準的(de)(de)(de):H57-3標準黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong):GB/T5231-2001是應用(yong)較廣的(de)(de)(de)黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong),可切(qie)削性(xing)(xing)好(hao)(hao),有(you)良好(hao)(hao)的(de)(de)(de)力學性(xing)(xing)能,能承受(shou)冷.熱壓(ya)力加(jia)(jia)工,易(yi)纖焊和焊接,對一般腐蝕有(you)良好(hao)(hao)的(de)(de)(de)穩定性(xing)(xing)！
