1. What is C17200 beryllium bronze?
1. Beryllium bronze is a copper-based tin-free alloy material with beryllium as the main element, which is a kind of age-precipitated strengthened copper alloy. It contains 7-5% beryllium and small amounts of elements such as nickel, chromium, titanium, etc. After quenching and aging treatment, the strength can reach 1250-1500MPa, which is close to the level of medium and strong steel.
2. Beryllium copper, also known as beryllium bronze, is generally the highest strength in copper alloys, has a high elastic coefficient, and has excellent elastic material characteristics. In addition, it has excellent heat resistance, fatigue resistance, corrosion resistance, and electrical resistance, and has more free space in the design of parts, making parts more miniaturized, and it is indeed a high-grade raw material.
3. C17200 is a typical precipitation-strengthened copper alloy. In addition to high strength, elasticity, hardness, corrosion resistance, high and low temperature resistance, non-magnetic, no sparks during impact and other characteristics. C17200 has very good machinability and can be processed into complex shapes using various molding methods.
4. The beryllium content of beryllium bronze is 2% 2%, and a small amount of 2% 0%) cobalt or nickel is added. The alloy can be strengthened by heat treatment. It is an ideal high-conductivity and high-strength elastic material.
2. What is the difference between Beryllium bronze C17300 and 17200
1. The properties and uses of C17300 beryllium copper are the same as those of C17200, with excellent cold working performance and good hot working performance, and are mainly used as diaphragms, diaphragms, bellows and springs. C17300 beryllium copper and has good cutting performance.
2. According to the composition of the alloy, the beryllium content of 2% and 6% is high conductivity (electrical, thermal) beryllium bronzeBeryllium content of 6% 0% is high-strength beryllium bronze. According to the manufacturing and forming process, it can be divided into cast beryllium bronze and deformed beryllium bronze. The internationally used beryllium bronze grade is headed by C.
3. In terms of mechanical properties, the tensile strength of C17300 beryllium bronze is as high as 1200MPa and the elongation is 15%. At the same time, its hardness reaches HV140-160, which is nearly twice as high as that of ordinary brass, and can maintain stable performance in high-strength and high-pressure environments. In terms of corrosion performance, C17300 beryllium bronze has good corrosion resistance.
4. C17300 beryllium bronze is a supersaturated solid solution copper-based alloy, which is a non-ferrous alloy with good combination of mechanical properties, physical properties, chemical properties and corrosion resistance.
After solution and aging treatment, it has high electrical conductivity, thermal conductivity, high hardness and wear resistance, high creep resistance and corrosion resistance.
5. The performance of C17300 high-strength beryllium bronze is equivalent to C17200, but the lead content of C17300 is 2%-6%, which increases the cutting coefficient of the alloy from 20% to 50% (100% for easy-cut brass), which greatly improves the processing performance of the alloy and has good adaptability to the precision requirements of precision parts.
