Comprehensive Analysis of TMg0.5 Magnesium Copper Rod / QMg0.5 Magnesium Bronze Plate

I. Chemical Composition and Material Properties

TMg0.5 Magnesium Copper Rod (C18665)

Composition: Copper (Cu) as the base (remainder), magnesium (Mg) content approximately 0.5%, total impurities ≤0.3% (such as iron, zinc, etc.), compliant with ASTM standards.

Characteristics: High conductivity (conductivity ≥90% IACS), excellent corrosion resistance, suitable for high-frequency conductive applications.

QMg0.5 Magnesium Bronze Plate

Composition: Presumed to be a domestic grade, part of the same series as QMg0.8 (magnesium content 0.7-0.85%), with magnesium content adjusted to 0.5%, enhancing heat resistance and conductivity in the copper matrix.

Characteristics: Slightly lower conductivity than TMg0.5, but superior high-temperature performance, suitable as an environmentally friendly alternative to cadmium bronze.

II. Mechanical Properties and Processing Techniques
