Product information

Model: QMg0.8 
QMg0.8 magnesium bronze (also known as magnesium bronze) is a copper-based alloy. By adding 0.8% magnesium, its performance is enhanced, while it contains trace amounts of iron (Fe), manganese (Mn), silicon (Si), etc. to optimize its properties. Here are its core performance indicators:
Mechanical properties
‌ Compressive strength: 540 MPa (for high-load pressure-bearing scenarios) ‌
‌ Yield strength: 400 MPa (starting point of plastic deformation) ‌
‌ Elastic modulus: 110 GPa (high rigidity) ‌
‌ Fracture strain: 15% (harmless deformation) ‌
Physical properties
‌ Density: approximately 8.8-8.9 g/cm³ (close to the density of pure copper, suitable for lightweight requirements) ‌
‌ Electrical conductivity: high, suitable for high-frequency conductive scenarios (such as cables, antennas) ‌
Corrosion resistance
It performs excellently in marine environments (seawater, salt fog) and industrial corrosive media. The magnesium element forms a protective film to slow down copper oxidation. ‌
Application scenarios
‌ Electronics and electrical: high-conductivity cables, semiconductor supports, waveguide tubes
‌ Machinery and aviation: high-strength bolts, aircraft antennas, turbine blade connectors
‌ Marine engineering: seawater pump valves, marine pipelines

Product parameter

Chemical composition 
The chemical composition of QMg0.8 magnesium bronze mainly includes:
‌Copper (Cu): As the main matrix element, its content constitutes the majority ‌
‌Magnesium (Mg): The addition amount is 0.8% (approximately 8000 ppm), which is the core additive element of this alloy ‌
‌Trace elements: Including iron (Fe), manganese (Mn), silicon (Si), etc., used to optimize performance (such as enhancing corrosion resistance, mechanical strength, etc.) ‌
‌Total impurity content: Generally ≤ 0.3% ‌
This alloy is an environmentally friendly material and can replace the cadmium-containing bronze materials.
