Main products CAS 7440-36-0 Antimony ingots Application: As the alloy hardener, it is used in metallurgy(冶金), accumulator(蓄电池), and war industry, chemical compounds(化合物) such as rubber(橡胶) industry, accumulator grid(蓄电池栅), alloy(合金), antimony bronze(锑青铜) and so on. It is also the raw material of antimony oxide. CAS 7440-31-5 Tin ingot(锡锭) Tin ingot is widely used as a coating(涂层/料) material in High-precision(高精密的) electronic products, and other requirements of precision welding (焊接)products, welding products, general electronics, food industry packaging, automotive and electrical(汽车和电器) industry, and high temperature resistant(抗/耐) products. Features(property性质/特点): 1. High purity(纯度)(Sn99.99 Sn99.95 Sn99.90), excellent weld ability, good infiltration(浸润/渗透). 2. Clean, beautiful. After welding, insulation(绝缘), high resistance(高电阻/热阻/抗), low ionic contamination(低离子污染), PCB board welding residual(残留) minimal(非常少). 3. Good oxidation resistance(高抗氧化性), low tin slag(低锡渣) and cost savings. 4. Solder(焊料) joint is bright, full and uniform.(焊接点光亮,焊接完整充分) 5. Economical and can produce the lowest consumption of the solid solder joints.(最低的固体焊接消耗量) Purity(%) As Fe Cu Pb(铅) Bi(铋) Sb(锑) Cd(镉) Zn Al Total 99.99 0.0005 0.0025 0.0005 0.0035 0.0025 0.002 0.0003 0.0005 0.0005 0.01 99.95 0.003 0.004 0.004 0.01 0.006 0.014 0.0005 0.0008 0.0008 0.05 99.90 0.008 0.0025 0.008 0.04 0.015 0.02 0.0008 0.001 0.001 0.1 ? CAS 1303-96-4 Borax(硼砂) Borax Physical and chemical properties Colorless translucent(半透明) crystals or white crystalline powder(粉末). Odorless, taste salty. (无臭,味咸)Soluble in water, glycerol(甘油), slightly(略) soluble in alcohol. Weakly alkaline solution(弱碱溶液). Borax in the air can slowly weathering(缓慢风化). Melting(融化) into a colorless glassy material. (熔成无色玻璃状物质) Use Mainly used in glass and enamel(搪瓷) industries. In the glass, can enhance(增强) UV transmission(紫外透谢) rate and improve the transparency(透明度) and heat resistance of glass. Products in the enamel, t
