T2 Copper Tube Copper Basket Copper Board Copper Powder Copper Copper Belt

The bronze stick is named after purple -red. Chinese copper processing materials can be divided into: ordinary copper (T1, T2, T3,), anaerobic copper (TU1, TU2, and high -purple, vacuum oxygen copper), off -oxygen copper (TUP, TUMN), and add a small amount of alloy elements Special copper (arsenic, copper, copper, silver copper). Copper's conductivity and thermal conductivity are second only to silver, and are widely used to make conductive and heat -conducting equipment. Copper has good corrosion resistance in the atmosphere, seawater and certain non -oxidized acids (hydrochloric acid, sparse), alkali, salt solution and various organic acids (acetic acid, citric acid) for chemical industry. It has good conductivity, heat conduction, corrosion resistance and processing performance, can be welded and welded. It contains less conductive and thermal impurities. Trace oxygen has little effect on the performance of conductive, thermal conductivity and processing, but it is easy to cause "hydrogen disease". Weldi

紫铜棒因呈紫红色而得名。中国紫铜加工材按成分可分为：普通紫铜(T1、T2、T3、)、无氧铜（TU1、TU2和高纯、真空无氧铜）、脱氧铜（TUP、TUMn）、添加少量合金元素的特种铜（砷铜、碲铜、银铜）。紫铜的电导率和热导率仅次于银，广泛用于制作导电、导热器材。紫铜在大气、海水和某些非氧化性酸（盐酸、稀）、碱、盐溶液及多种有机酸（醋酸、柠檬酸）中有良好的耐蚀性，用于化学工业。有良好的导电、导热、耐蚀和加工性能,可以焊接和钎焊。含降低导电、导热性杂质较少,微量的氧对导电、导热和加工等性能影响不大，但易引起“氢病”，不宜在高温（如>370℃）还原性气氛中加工（退火、焊接等）和使用。

用途
紫铜棒的用途比纯铁广泛得多，每年有50%的铜被电解提纯为纯铜，用于电气工业。这里所说的紫铜，确实要纯，含铜达99.95%以上才行，极--少量的杂质，特别是磷、砷、铝等，会大大降低铜的导电率。铜中含氧(炼铜时容易混入少量氧)对导电率影响很大，用于电气工业的铜一般都必须是无氧铜。另外，铅、锑、铋等杂质会使铜的结晶不能结合在一起，造成热脆，也会影响纯铜的加工。这种纯度很高的纯铜，一般用电解法精制：把不纯铜(即粗铜)作阳极，纯铜作阴极，以铜溶液为电解液。当电流通过后，阳极上不纯的铜逐渐熔解，纯铜便逐渐沉淀在阴极上。。
紫铜是比较纯净的一种铜，一般可近似认为是纯铜，导电性、塑性都较好，但强度、硬度较差一些。

紫铜棒特性
特性：高纯度，组织细密，含氧量极-低。无气孔、沙眼、疏松，导电性能极-佳，电蚀出的模具表面精度高，经热处理工艺，电极无方向性，适合精打，细打，具有良好的热电道性、加工性、延展性、防蚀性及耐候性等。
