說到粉末冶金工藝技術(shù)以及材料，我們南方粉末冶金是再熟悉不過了，我們南方粉末冶金成立于1984年，至今已有30幾年的發(fā)展。在行業(yè)內(nèi)我們已經(jīng)是獨(dú)樹一幟，有著其他公司無法替代的地位。我們就來給大家簡單講講粉末冶金工藝和傳統(tǒng)的冶金工藝有哪些突出的優(yōu)點(diǎn)。1、我們粉末冶金工藝是在低于基體金屬的熔點(diǎn)下進(jìn)行的，因此可以獲得熔點(diǎn)、密度相差懸殊的多種金屬、金屬與陶瓷、金屬與塑料等多相不均質(zhì)的特殊功能復(fù)合材料和制品。2、另一方面我們提高了材料性能。用特殊方法制取的細(xì)小金屬或合金粉末，凝固速度極快、晶粒細(xì)小均勻，保證了材料的均勻，性能穩(wěn)定，以及良好的冷、熱加工性能，且粉末顆粒不受合金元素和含量的限制，可提**化相含量，從而發(fā)展新的材料體系。3、一點(diǎn)是利用各種成形工藝，我們可以將粉末原料直接成形為少余量、無余量的毛坯或凈形零件，很重要的一點(diǎn)就是大量減少機(jī)加工量。提高材料利用率，降低成本。我們一般的粉末冶金的品種繁多，主要有：鎢等難熔金屬及合金制品；；硬質(zhì)合金，用于制造切削和耐磨中的鉆頭、車刀、銑刀，還可制造模具等；Cu合金、不銹鋼及Ni等多孔材料，用于制造燒結(jié)含油軸承、燒結(jié)金屬過濾器及紡織環(huán)等。隨著粉末冶金生產(chǎn)技術(shù)的發(fā)展。</p><div
