Brass bars possess high strength, good plasticity, and are suitable for cold and hot processing, with excellent weldability and corrosion resistance. They exhibit good mechanical properties, plasticity in the hot state, machinability, weldability, and corrosion resistance. Those composed of copper and zinc are called ordinary brass, while those made from two or more elements are known as special brass. Their properties vary depending on the elements and the proportion of copper used. Additionally, brass bars can be manufactured in different specifications according to actual needs.
Brass bars have high strength, good plasticity, and are suitable for cold and hot processing, with excellent weldability and corrosion resistance. They are used in condenser and heat dissipation tubes, serpentine tubes, siphon tubes, and cooling equipment components. They offer good mechanical properties, plasticity in the hot state, machinability, weldability, and corrosion resistance. They are also used for various deep-drawn and bent load-bearing parts, such as pins, nuts, pressure gauge springs, heat dissipation components, and ring-shaped parts. Lead brass plate is a widely used type of brass with good mechanical properties and excellent machinability. It can withstand cold and hot pressure processing and is used for various structural parts in machining and stamping, such as gaskets and bushings. Tin brass plate has high corrosion resistance, good mechanical properties, and excellent pressure processability in both cold and hot states. It is suitable for corrosion-resistant parts on ships, as well as components and conduits in contact with media like steam and oil. Brass bars exhibit good mechanical properties, low electrical and thermal conductivity, and excellent corrosion resistance, though they are prone to stress corrosion cracking. They are used for critical corrosion-resistant parts and components in the weak current industry.
H90 High-Precision Brass Bar Characteristics and Application Range: It has higher strength than copper (though it is among the lowest in ordinary brass), good electrical and thermal conductivity, high corrosion resistance in atmospheric and freshwater environments, and excellent plasticity. It is easy to process with cold and hot pressure, weld, forge, and tin-plate, with no tendency for stress corrosion cracking. Hot working temperature: 850–950°C; annealing temperature: 650–720°C; low-temperature annealing for stress relief: 200°C.
