Copper strips can be classified according to different grades and can be roughly divided into brass strips, red copper strips, bronze strips, and white copper strips.
Copper strips are divided into hot-rolled strips and cold-rolled strips. The thickness of hot-rolled strips is generally 4~25mm, and the thickness of cold-rolled strips is between 0.2mm~15mm. The maximum width is 2500mm and the maximum length is 6000mm. .
Copper plate and strip
The thickness of copper strips can reach 50mm. Its mechanical properties are tensile strength: ≥315; elongation: ≥30 (Note: room temperature tensile mechanical properties of other types of plates and strips except lock and bell-making plates and strips); sample size: diameter >2.0～4.0; heat treatment specifications: thermal processing temperature 650～850℃; annealing temperature 600～700℃; low temperature annealing temperature to eliminate internal stress 270～300℃. Copper plates and strips have good mechanical properties, good plasticity in the hot state, acceptable plasticity in the cold state, good machinability, easy fiber welding and welding, and corrosion resistance, but prone to corrosion and cracking. In addition, they are cheap and are widely used. A common variety of copper.
Brass plate and strip
Brass strip is a widely used lead brass. It has good mechanical properties and good machinability. It can withstand hot and cold pressure processing. It is used in various structural parts for cutting and stamping processing, such as gaskets. , bushings, etc. Tin brass plate has high corrosion resistance, good mechanical properties, and good pressure processability in cold and hot states. It can be used for corrosion-resistant parts on ships and parts in contact with steam, oil and other media. catheter.
White copper plate and strip
White copper plate and strip is a copper alloy with nickel as the main alloy. Cupronickel rods based on copper-nickel alloy and adding third elements such as zinc, manganese, aluminum, etc. are accordingly called zinc-nickel copper rods, manganese-nickel-nickel rods, aluminum-nickel-nickel rods, etc. Copper-nickel alloy has good corrosion resistance, medium strength, high plasticity, can be processed by hot and cold pressure, and has good electrical properties. In addition to being used as structural materials, it is also an important high resistance and thermocouple alloy. Cupronickel plates and strips are divided into five categories: ordinary cupronickel plates and strips, iron cupronickel plates and strips, manganese cupronickel plates and strips, zinc cupronickel plates and strips, and aluminum cupronickel plates and strips. White copper plate and strip has good corrosion resistance, medium strength, high plasticity, can be processed by hot and cold pressure, and has good electrical properties. In addition to being used in structural materials, it is also an important high resistance and thermocouple alloy.
