Brass plate is an alloy of copper and zinc. A simple brass plate is a copper zinc binary alloy. Brass plate is a widely used lead brass with good mechanical and processing properties, and can withstand cold and hot pressure processing. It is used for cutting and stamping various structural parts, such as washers, bushings, etc. The main purpose of adding lead to this product is to improve machinability and wear resistance. Lead has almost no effect on the strength of brass plates.

So what are the differences between copper plate and brass plate? Below is an introduction for you.

1. Different composition: Red copper is very pure, almost pure copper, with outstanding conductivity and plasticity, slightly weak strength and hardness. Brass plate also contains other low-cost alloys, which have slightly weaker conductivity and plasticity compared to red copper, but higher strength and hardness.

2. Different functions: Red copper has a copper content of 99.9% and excellent conductivity, thermal conductivity, resistance, weldability, and corrosion resistance. The density of brass plate is higher than that of red copper, with impurities, good corrosion resistance, and lower conductivity.

3. Different uses: The former is commonly used in the manufacturing of conductive and thermal conductive devices. Due to its good corrosion resistance, it is also often used in the chemical industry. It can be processed into semi-finished products or semi-finished products through cold or hot plastic processing. The latter is corrosion-resistant and is commonly used in elastic components, hardware, and decorative materials.

Because we don't know what method the ancients used to smelt zinc ore or Smithsonite, we don't know much about the use of brass plate in ancient times. The boiling point of zinc is lower than that of copper, and charcoal will also heat the zinc ore when heating copper, so it is difficult to prevent zinc evaporation. The Romans may have been the first to use this method on a large scale, but craftsmen who melted bronze may have unintentionally produced H6 brass plates before this, as the difference between tin and zinc was not initially clear. In fact, in the early days, in order to make things more complicated, they did use H62 brass plates to make coins, but initially, H62 brass plates were more expensive than others.

But starting from the Middle Ages, before it was used for pots and plates, the substance was a consumer product and was only used for commemorative tombstones. Starting around 1230 AD, product products have been popular in Europe for about 300 years because they are much cheaper than large sculptures. The copper statue of Archbishop Wilp, which dates back to 1231, is known to have been made from it. The process of casting this product involves first mixing crushed zinc ore and charcoal with copper blocks to heat them together, then heating and melting the alloy, and then pouring the molten metal into the mold.
