What Copper Plate and Sheet Grades Does Zhongtongweiye Supply?

Zhongtongweiye serves many industries with copper plate and sheet products. The company focuses on consistent quality and reliable supply. Buyers often ask about the exact grades available. This article explains the main copper grades Zhongtongweiye supplies. It also covers their typical properties and uses. The goal is to help procurement teams make informed choices.

Pure Copper Grades for Electrical and Thermal Needs

Zhongtongweiye supplies several pure copper grades. C11000 is a top choice for electrical work. It offers high conductivity and good ductility. C10200 provides similar performance with low oxygen content. C10100 delivers even higher purity for critical applications. These copper sheet grades work well in busbars and transformers. They also suit heat exchangers and gaskets. For thermal management, C11000 copper plate remains a common pick. It balances cost and performance effectively. Each grade meets ASTM and GB standards. Zhongtongweiye tests conductivity and surface finish before shipping.

Copper Alloy Grades for Strength and Corrosion Resistance

Beyond pure copper, Zhongtongweiye supplies alloy grades. C26000 brass offers excellent cold working ability. It resists corrosion in many environments. C28000 brass provides higher strength for structural parts. C51000 phosphor bronze delivers good fatigue resistance. C52100 phosphor bronze adds more tin for extra hardness. These copper alloy plate grades serve marine and industrial uses. They also appear in springs and electrical connectors. C70600 cupronickel resists seawater corrosion. C71500 cupronickel handles higher temperatures. Zhongtongweiye stocks these alloys in various thicknesses. Customers can request custom cuts and tempers.

Beryllium Copper and Specialized Grades

Some projects need beryllium copper for high strength. C17200 offers exceptional hardness after aging. C17510 provides better conductivity with moderate strength. These copper plate grades work in molds and bearings. They also suit aerospace and oil tool parts. Zhongtongweiye supplies them in mill-hardened or annealed states. Another specialized grade is C19400. It balances conductivity and strength for lead frames. C19210 adds iron and phosphorus for heat resistance. These grades support electronics and automotive connectors. Each order includes a mill test report. This report confirms chemical and mechanical properties.

Thickness, Temper, and Finish Options

Zhongtongweiye offers copper sheet and plate in many sizes. Thickness ranges from 0.1 mm to 100 mm. Widths go up to 1,200 mm for sheets. Plates can reach 2,000 mm in width. Tempers include soft, half-hard, and full-hard. Surface finishes cover mill, bright, and brushed. Some grades come with protective film. This film prevents scratches during shipping. Buyers can specify edge conditions too. Slit, sheared, or sawed edges are available. Zhongtongweiye also provides custom slitting and cutting. These services reduce waste and save time.

Quality Control and Industry Applications

Quality control matters for copper plate and sheet grades. Zhongtongweiye follows strict inspection steps. Spectrometers verify chemical composition. Tensile tests check mechanical strength. Hardness tests confirm temper consistency. Dimensional checks ensure accurate thickness and width. These steps meet ISO 9001 requirements. The company serves electrical, marine, and automotive sectors. It also supports HVAC, electronics, and aerospace industries. Each customer gets a dedicated sales contact. That contact tracks orders from quote to delivery. Fast turnaround helps clients meet tight deadlines.

How to Choose the Right Grade

Selecting a copper grade depends on your application. For high conductivity, choose C11000 or C10200. For corrosion resistance, consider C70600 or C71500. For strength and wear resistance, pick C17200 or C52100. Consider temper and thickness as well. A soft temper bends easily. A hard temper resists deformation. Zhongtongweiye offers technical guidance. Engineers can help match a grade to your needs. They also provide samples for testing. This support reduces risk before full production.

Conclusion: Reliable Supply for Diverse Copper Needs

Zhongtongweiye supplies a broad range of copper plate and sheet grades. Pure copper grades serve electrical and thermal duties. Alloy grades add strength and corrosion resistance. Specialized grades like beryllium copper meet extreme demands. The company backs each order with testing and documentation. It also offers flexible sizes, tempers, and finishes. For buyers seeking consistent copper sheet and plate, Zhongtongweiye provides a practical source. Their focus on quality and service helps industries build better products.
