Product Advantages
Precise Composition Control
We strictly select high-purity copper containing 0.2% to 2.7% beryllium. Precisely proportioned and weighed technology is used to ensure a stable alloy chemical composition, guaranteeing consistent mechanical properties and conductivity in beryllium copper castings.
Precision Melting Process
Smelting is performed in an electric induction furnace, controlled between 1100 and 1300°C. Flux is introduced to prevent oxidation impurities, ensuring a pure, inclusion-free melt and enhancing the internal quality and durability of the castings.
Diverse Casting Processes
Combining lost wax casting, sand casting, and metal mold casting techniques, we achieve precise casting for various product sizes and shapes. Metal mold casting ensures dimensional tolerances of less than ±0.1mm for medium and high-volume production, improving processing consistency.
Heat Treatment
Solution treatment at 760 to 815°C, followed by rapid quenching and aging at 315 to 370°C, promotes uniform distribution of fine precipitates and improves hardness and strength.
Quality Control
1. Chemical Tests
- Regular testing is done by means such as spectroscopy to check that content to specification is met in the bronzes castings of beryllium.
2. Non - Destructive Testing (NDT)
- Methods such as ultrasonic testing, X-ray testing, and magnetic particle testing check internal and surface faults in the castings in forms of inclusions, cracks, and porosity.
3. Mechanical Testing
- Tensile testing, testing by hardness, and testing by impact is carried out to validate the mechanical properties of the castings to check that they have strength, hardness, and durability needed by standards.
Safety Considerations
Beryllium is an unsafe material, and proper caution has to be practiced while making it. Necessary protective equipment (PPE) in the shape of mask (respirators) gloves should be worn by workers. Proper ventilatory systems should be implemented to prevent inhaling dust or fume of beryllium. Proper wastage management systems should be implemented to treat wastage carrying beryllium in an appropriate manner.
