Frequently Asked Questions (FAQ)

Q:What is the primary chemical composition of this brass alloy?

This alloy consists of 60.0% to 63.0% Copper (Cu) and 2.5% to 3.7% Lead (Pb), with the remainder being Zinc (Zn) and minimal impurities (Iron content ≤ 0.35%).

Q:Why does this brass exhibit outstanding machining performance?

The inclusion of lead (2.5%–3.7%) acts as an efficient lubricant and chip breaker during cutting. This ensures clean chip removal without sticking to the blade, making it highly suited for CNC and high-speed automatic lathes.

Q:What are the key thermal and electrical properties?

The alloy has a density of 8.50 g/cm³, a melting point range of 885–900 ℃, a thermal conductivity of 115 W/(m·K), and electrical conductivity rated at 26 % IACS (in its annealed state).

Q:Is this alloy suitable for electrical connectors?

Yes, thanks to its balanced electrical conductivity (26% IACS) and good heat dissipation, it is a preferred material for connector terminals, joints, and terminal blocks.

Q:Can it be processed through cold working?

Yes, it possesses good cold working characteristics, enabling slight bending, stamping, and easy processing under both cold and hot conditions with high yield rates.
