Golden Sunbird Metals offers a comprehensive selection of copper alloys, including free-cutting and leaded brasses (C36300, C38500, C37700, C35000, C35300), naval brass, phosphor bronze, aluminum bronze, cupronickel (C70400, C70600, C71000, C71500), ETP copper (C11000), OFHC copper (C10100, C10200), and high-performance copper-beryllium alloys (C17200 Alloy 25, C17300, C17500, C17510). All meet ASTM specifications.

We supply copper alloys in pipes and tubes (seamless, welded, U-bend, finned, condenser), plates and sheets, bars and rods (round, square, hexagonal, rectangular), forgings, and custom shapes. Products are available in standard and custom dimensions to suit your project needs.

Our copper alloys provide outstanding electrical and thermal conductivity, excellent corrosion resistance (especially in seawater and marine environments), superior machinability, wear resistance, antimicrobial properties, high strength, and malleability—making them ideal for demanding applications across multiple industries.

Cupronickel alloys (C70600, C71500) and aluminum bronze excel due to exceptional corrosion resistance, biofouling resistance, and long service life in seawater desalination, shipbuilding, offshore platforms, and heat exchangers. They also resist stress corrosion cracking and hydrogen embrittlement.

ETP copper (C11000) and OFHC copper (C10100, C10200) deliver maximum conductivity, while copper-beryllium alloys (C17200 series) combine high strength, fatigue resistance, non-sparking properties, and excellent conductivity—perfect for connectors, springs, switches, and precision electronic components.

Yes. Brass alloys (including free-cutting and leaded grades) offer superior machinability, corrosion resistance, and cost-effectiveness for plumbing fittings, valves, HVAC systems, architectural elements, and decorative applications.

All products fully comply with ASTM standards (e.g., B111, B466, B171, B196, B194) and are engineered to surpass industry requirements. Material Test Reports (MTRs) and full traceability are provided for quality assurance in critical applications.

Brass is an alloy of copper (typically 55–95%) and zinc (5–45%). The exact ratio varies to achieve different colors, strengths, and workability. Small amounts of other elements (e.g., lead, tin, aluminum) may be added for specific properties.

It is primarily copper (55–65%) and zinc (30–40%), with added lead (low-, medium-, or high-leaded grades). Lead remains as tiny globules that act as internal lubricants and chip breakers.

Aluminum bronze is primarily copper (88–92%) with 4–14% aluminum, plus small amounts of iron, nickel, manganese, silicon, or tin for enhanced properties.

Beryllium copper (BeCu, also called copper beryllium or beryllium bronze) is a premium copper alloy containing 0.5–3% beryllium, capable of achieving the highest strength of any copper alloy through age-hardening.

Copper-nickel alloys (cupronickel or CuNi) are copper-based alloys with nickel as the main alloying element (typically 10% or 30%), plus small iron and manganese for added performance.
