The difference between copper row and brass row and price influence factors
Copper bars, also known as copper bus bars or copper bus bars, are made of copper. Copper bars are long conductors with rectangular or chamfered (rounded) rectangular cross-sections (but nowadays, rounded copper bars are usually used to avoid the phenomenon of tip discharge), which plays a role in conveying current and connecting electrical equipment in the circuit. . Copper bars are widely used in electrical equipment, especially complete power distribution devices. Copper bars can be divided into copper bars and brass bars according to their composition. Red copper bars are copper bars made of pure copper, and brass bars contain copper and zinc, which are copper-zinc alloy products.
The difference between copper row and brass row:
1. The composition difference between copper bars and brass bars:
copper bars: the copper content reaches 99.9%. Brass row: about 60% copper; about 40% zinc; individual grades contain about 1% lead, which is impurity.
2. The strength difference between copper bars and brass bars:
copper bars: lower. Brass row: higher.
3. The difference in conductivity between copper bars and brass bars:
copper bars: higher. Brass row: lower.
4. The difference in corrosion resistance between red copper bars and brass bars:
red copper bars: better. Brass row: poor.
5. The difference in cutting performance between copper bars and brass bars:
copper bars: poor. Brass row: better
6. The price difference between copper row and brass row.
Due to the difference in copper content between copper bars and brass bars, the price of copper bars is usually much more expensive than that of brass bars. Generally, the price of copper bars will fluctuate with the spot copper prices on the market.
