The copper rod is a kind of non-ferrous metal processing bar, which has better processing performance and high electrical conductivity. Mainly divided into brass rods (copper-zinc alloy, cheaper), copper rods (higher copper content).
The brass rod is a rod-shaped object made of an alloy of copper and zinc, and is named for its yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, ship parts, and shells for guns. Different zinc content will also have different colors. For example, if the zinc content is 18%-20%, it will be reddish yellow, and if the zinc content is 20%-30%, it will be brownish yellow. In addition, the sound of brass is unique, so the oriental instruments such as cymbals, cymbals, bells, and numbers, as well as Western brass instruments, are made of brass.
Super 100 – a series of Macroporous Adsorbent Resin designed for the polishing purification. These resins have optimized pore structure, excellent chemical and pH stability. They are made of polystyrene, with the advantages of high mechanical strength, easy column packing and high resolution. These resins are able to maintain high capacity of target products (e.g insulin) after soaked in 1mol/L NaOH. As the result, it can be considered to replace C18 silica gel in some cases.
