Buck Copper Group Limited Company offers CuZn10 square brass tubes, also known as H90 brass, composed of 90% copper and 10% zinc. This alloy is widely used in plumbing, architectural trim, heat exchangers, and industrial fluid transport due to its excellent corrosion resistance and thermal conductivity. The tubes are manufactured to international standards such as ASTM, AISI, JIS, EN, and GB.
CuZn10 brass is a standard alloy for applications requiring both formability and strength, with typical tensile strength ranging from 300 to 400 MPa and elongation of 15% to 25%. The material’s machinability and solderability make it a preferred choice for precision components in construction and automotive sectors. Surface finishes include mill, polished, bright, oiled, hairline, brush, mirror, or sand-blasted options, depending on the application.
These square brass tubes are available in side lengths from 30 mm x 30 mm to 300 mm x 300 mm, with wall thicknesses between 1 mm and 5 mm. Custom lengths and sizes can be produced to meet specific project requirements. Buyers in the construction, automotive, and manufacturing sectors often source these tubes for electrical appliances, refrigeration systems, and high-pressure fluid transport.

Before placing an order, confirm the exact alloy grade (CuZn10/H90) and verify that the mechanical properties, such as tensile strength and elongation, meet your project’s requirements. Request material test reports (MTRs) to validate composition and performance, as these directly impact durability in applications like plumbing or heat exchangers.
Discuss the side length, wall thickness, and surface finish options with the supplier to ensure the tubes match your specifications. Clarify packaging methods, such as bundled or crated shipments, to prevent damage during transit. Confirm Incoterms (e.g., EXW, FOB, CIF) and the port of loading, typically Qingdao, to align with your logistics and cost structures.
For quality checks, inspect the tubes for dimensional accuracy, surface defects, and material consistency upon arrival. Use calipers to verify side lengths and wall thicknesses, and conduct a visual inspection for cracks or corrosion. Request certifications such as ISO or ASTM compliance to ensure the material meets industry standards for your application.
