The manufacturer of beryllium copper shrapnel with rebound times of 100,000+ tells you the processing performance and use industry of beryllium copper

Beryllium copper is a commonly used raw material for shrapnel manufacturers. It is a high-grade elastic material with good performance among copper alloys. It has high strength, elasticity, hardness, fatigue strength, low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, and no sparks due to impact. A series of excellent physical, chemical and mechanical properties are popular among various industries when choosing to make shrapnel. Beryllium copper, also known as beryllium bronze, is the 'king of elasticity' in copper alloys. It is often produced in large quantities every day in hardware shrapnel manufacturers. After solution aging heat treatment, products with high strength and high conductivity can be obtained. Beryllium bronze is divided into two categories. The analysis is based on the alloy composition. The beryllium bronze with a beryllium content of 0.2% to 0.6% is high-conductivity (electrical and thermal) beryllium bronze; the beryllium bronze with a beryllium content of 1.6% to 2.0% is a high-strength beryllium bronze. According to the manufacturing process, it can be divided into cast beryllium bronze and deformed beryllium bronze. The internationally used beryllium bronze alloy grades are led by C. There are two types of deformed beryllium bronze, C17000, C17200 (high-strength beryllium bronze) and C17500 (high-conductivity beryllium bronze). Corresponding to the beryllium bronze often used in the casting of shrapnel manufacturers are C82000, C82200 (high-conductivity cast beryllium copper) and C82400, C82500, C82600, C82800 (high-strength wear-resistant cast beryllium copper). The history of China's production of beryllium bronze is almost synchronized with the former Soviet Union, the United States and other countries, but the only grades listed in the national standard are high-strength beryllium bronze QBe1.9, QBe2.0, and QBe1.7. Because beryllium bronze has good comprehensive properties. Its mechanical properties, namely strength, hardness, wear resistance and fatigue resistance rank first among copper alloys. Its electrical conductivity, heat conduction, non-magnetic, anti-sparking and other properties cannot be compared with other copper materials. In the solid solution and soft state, the strength and conductivity of beryllium bronze are at the lowest value. After work hardening, the strength is improved, but the conductivity is still low. After aging heat treatment, its strength and electrical conductivity increase significantly. At the same time, beryllium copper shrapnel manufacturers often encounter many process and quality problems in the production and processing. The difficulty of gold-plated beryllium copper shrapnel is the heat treatment of beryllium copper. Many manufacturers have found that they cannot find a suitable quenching supplier, resulting in inconsistent product flexibility, which affects product quality. Only a number of quenching suppliers are stable. Gold-plated beryllium copper shrapnel is more expensive, so the design precision is relatively high. The key is that there is often a bending design. You can produce it without any problems, but it is slightly deformed after quenching, and it is also prone to quality accidents. Therefore, relatively experienced designers are required to choose different processing techniques according to different grades of beryllium copper. There are many grades of beryllium bronze with different chemical compositions. Before quenching, it is necessary to know the brand, technical requirements, and product dimensions of beryllium bronze. For different brands, different technical requirements, and different product sizes, the quenching heating temperature, holding time, cooling method, etc. should be analyzed and detailed in detail. Processing. The machining performance, welding performance and polishing performance of beryllium bronze are similar to those of general high copper alloys. In order to improve the machining performance of the alloy to meet the precision requirements of precision parts, a high-strength beryllium bronze (C17300) with a lead content of 0.2% to 0.6% has been developed in recent years. Its various properties are equivalent to C17200, but the alloy’s The cutting coefficient has been increased from the original 20% to 60% (100% for free-cutting brass). Because beryllium copper has so many advantages, it has been widely used in electronics, communications, automotive, aerospace, military and other industries, and its characteristics are also in the elastic performance, which is unique and will never let the big guys down. of. In the processing of beryllium copper shrapnel manufacturers, the service life of beryllium copper stamping dies is long, and the cost of the mold and the continuity of production are estimated. For the beryllium copper shrapnel manufacturers, the expected service life of the mold is very important. When the hardness meets the requirements, the insensitivity of beryllium copper to mold temperature stress can greatly improve the service life of the mold. Before determining the use of beryllium copper mold materials, the yield strength, elastic modulus, and thermal conductivity of beryllium copper should also be considered. Rate and temperature coefficient of expansion. The resistance of beryllium copper to thermal stress is much stronger than that of die steel. At the same time, among beryllium copper shrapnel manufacturers, beryllium copper is very suitable for surface finishing, which can be directly electroplated, and the adhesion performance is very good, and the polishing treatment of beryllium copper is also very easy. To put it simply, the beryllium copper shrapnel stamping die designed by engineers with 15 years of experience during stamping production has better precision control, and the size and structure are easier to shape. The number of springbacks after solution treatment can reach 100,000+ times. Without deformation. Hardware, 15 years of ingenuity focused on beryllium copper shrapnel manufacturer, 20,000+ sets of shrapnel mold processing and production experience, stamping accuracy can reach 0.01mm, 16 QC layers are strictly for quality control.
