Copper is one of the earliest metals used by humankind. Due to its ease of mining, refining, and processing, copper is widely used in the electrical engineering, construction, and hardware industries. Copper can be classified into three categories based on the proportion of copper and other metals: bronze, brass, and red copper (purple copper). Red copper and brass are common materials for making terminal blocks, with Stamped Copper Terminals having the most widespread applications.
Red copper, also known as pure copper, is elemental copper, named for its purplish-red color. It is industrial pure copper, containing a certain amount of oxygen, and can be considered approximately pure copper. Precision Copper Stamping Parts often use this type of pure copper as a high-quality raw material. Its melting point is 1083℃, it does not undergo allotropic transformation, and its relative density is 8.9, five times that of magnesium. Its mass for the same volume is about 15% heavier than ordinary steel. After an oxide film forms on its surface, it appears purple. Copper has good electrical conductivity and ductility, but poor strength and hardness. It possesses excellent thermal conductivity, ductility, and corrosion resistance. Trace impurities in copper can severely affect its electrical and thermal conductivity. If recycled copper is used to make terminals, the presence of other metals will create resistance, easily leading to poor contact and current loss at the Red Copper Stamping Parts, posing safety hazards and significantly reducing the lifespan of the cables and terminals.
Brass is an alloy composed of copper and zinc. Ordinary brass consists only of copper and zinc, while special brass is composed of two or more elements. Some Copper Pressed Components are also made of brass. Brass has strong wear resistance and is commonly used in the manufacture of valves, water pipes, air conditioner meters, and radiator connections, etc.
Brass terminals have a yellowish surface, never reddish, and produce a crisp sound when dropped. They are hard and wear-resistant. Copper terminals, on the other hand, have a reddish or slightly purplish surface and produce a duller, less crisp sound when dropped. The difference in material properties directly impacts the appearance and physical characteristics of Copper Pressed Stamped Parts. Copper is more expensive than brass, hence the higher price of copper terminals.
Frequently Asked Questions
Q: What are the differences in material composition between red copper and brass, commonly used in the manufacture of Electrical Metal Stamping?
A: Red copper is pure copper, a type of industrial copper containing only trace amounts of oxygen impurities. Brass is a copper-zinc alloy; ordinary brass consists only of copper and zinc, while special brass may contain two or more additional metallic elements. These two types are the most common base materials for stamped terminals.
Q: What are the potential hazards of using recycled copper stamped pressing cutting assembly parts?
A: Recycled copper contains various metallic impurities, which increase the conductive resistance of the terminals, easily leading to poor contact and current loss. This not only shortens the lifespan of cables and terminals but also poses electrical safety hazards such as overheating and short circuits.
Q: What are the advantages of using high-purity red copper raw materials in pressed copper stamping sheets?
A: 99.99% high-purity copper has extremely low impurity content, fully retaining the excellent electrical conductivity, thermal conductivity, and corrosion resistance of red copper. During operation, the current transmission is stable, with less heat loss, making it suitable for various electrical wiring scenarios and offering greater long-term reliability.
