Our products not only cover China but are also exported to countries worldwide. With their high cost-effectiveness and superior performance, they have become the first choice for many international buyers. Choosing us means choosing a long-term strategic partner who understands technology, has production capacity, and values integrity.

Technical Parameters and Core Advantages

Chemical Composition and Standards: Strictly adhering to ASTM C44300 and Chinese standard H62-1, the copper content is consistently between 61% and 63%, and the lead content is extremely low, meeting environmental protection requirements. Tensile Strength: 330–380 MPa in the annealed state, increasing to 500–600 MPa after cold working, fully meeting the structural requirements of high-pressure heat exchangers.

Hardness and Elongation: Brinell hardness 60–100 HB (adjustable), elongation ≥8% (up to 40% in the annealed state), combining high strength with excellent plasticity.

Thermal Conductivity and Weldability: Thermal conductivity approximately 109 W/(m·K), comparable to 304 stainless steel; supports TIG welding and brazing, with a small heat-affected zone and low cracking resistance.

Corrosion Resistance Key Data: In salt spray tests simulating seawater environments, our ASTM C44300 Brass Plates And Blocks H62-1 exhibits significantly superior dezincification resistance compared to ordinary brass, which is why it is specified for use in power plants and desalination plants.

Processing Technology and Production Capacity

Full Size Coverage: Our equipment fleet can produce copper plates and blocks with diameters/side lengths from 15mm to 2000mm. Whether you're making precision instrument parts or large marine bearings, our processing capabilities cover the entire range.

Precision and Efficiency: With 30 machining centers, we guarantee a simple machining tolerance of 0.5mm per side. For ASTM C44300 Brass Plates and Blocks H62-1, we support both "net size" and "allowance size" delivery options, minimizing your scrap losses.

Lead Time Highlights: Thanks to 25 electric furnaces operating simultaneously and a robust mold library, we can achieve "rapid prototyping" for standard-sized copper plates and blocks, and offer highly competitive delivery times for bulk orders.

Applicable Scenarios

Marine Engineering: Marine condensers, desalination plant evaporator tube sheets, marine pump bodies, valve parts. Its resistance to seawater impact corrosion is unmatched by ordinary brass.

Power Energy: High-temperature and high-pressure heat exchangers for inland thermal power plants, and heat exchange equipment for petrochemical refineries.

General Machinery: Requires wear-resistant and corrosion-resistant copper bearings, copper gaskets, and copper nuts. As a professional manufacturer of copper bearings (annual production of 20,000 tons), we have in-depth knowledge of material selection for different working conditions. ASTM C44300 Brass Plates and Blocks H62-1 is an ideal base material due to its self-lubricating and heat-resistant properties.

Construction and Weather-Resistant Components: If you need decorative components or rainwater pipes for outdoor use, C44300's weather resistance and resistance to stress corrosion cracking will significantly extend aesthetics and service life.

We can customize according to your requirements

Material Customization: Not only ASTM C44300 Brass Plates and Blocks H62-1, but any bronze or brass blend.

Dimensional Tolerances: Not only standard plates and blocks, but also semi-finished products can be machined, with tolerances strictly controlled to 0.01mm.

Delivery Date: Rush orders are given priority.
