Import Bronze Sheets And Plates — Buy in wholesale FOB from Supplier in China

Xuzhou Yutai Aluminum Manufacturing Co., Ltd. produces phosphor bronze sheets and plates in grades C5191 (CuSn6) and C5210 (CuSn8) at their facility in Tang Zhang Industrial Park, Tongshan District, Xuzhou, Jiangsu Province, China. Hot rolled material is available in thickness from 9 mm to 50 mm, with maximum width of 600 mm and maximum length of 2000 mm. Thinner cold-rolled strip in soft, quarter-hard (H/4), half-hard (H/2), hard, and extra-hard tempers covers the >0.5 mm to 12 mm thickness range, also with 600 mm maximum width and 2000 mm maximum length. The tin content distinguishes the two grades: C5191 contains approximately 6% tin by weight, while C5210 contains approximately 8% tin, with both grades alloyed with 0.03-0.35% phosphorus for deoxidation and wear resistance. These alloys exhibit excellent spring characteristics, fatigue resistance, and electrical conductivity suitable for demanding engineering applications.

Material specification extends to imitation-gold copper alloy sheets under Alloy No. 18, supplied in soft temper with thickness 0.5-10 mm, maximum width 600 mm, and length 1000-2000 mm. Additionally, the supplier lists C18000 nickel-silicon-chromium copper sheets in hard temper, available from 2.0 mm thickness with 600 mm width and 1200 mm maximum length. Phosphor bronze derives its engineering value from the tin addition strengthening the copper matrix through solid solution strengthening, while phosphorus improves fluidity during casting and subsequent machinability. The H/4, H/2, hard, and extra-hard tempers indicate progressive cold reduction with corresponding increases in tensile strength and yield point, accompanied by reduced elongation. Standard industry practice for spring contact applications specifies C5210 in hard or extra-hard temper due to its higher elastic limit and better stress relaxation resistance at elevated temperatures.

Primary applications for these phosphor bronze sheets include electrical spring contacts, connector terminals, switch components, and electromagnetic shielding in the electronics sector; corrosion-resistant marine hardware, pump impellers, and valve components for shipbuilding; and automotive terminals, gaskets, and bearing surfaces. The C18000 alloy serves applications requiring higher thermal and electrical conductivity with maintained strength, such as resistance welding electrodes and electrical switchgear. Buyers should confirm with Xuzhou Yutai their exact production capacity for each alloy-temper combination, typical mill lead times from order confirmation, minimum order quantities per thickness and temper, and whether custom dimensions or tighter tolerances are available beyond the published ranges. The supplier's response rate is recorded at 0.00%, so direct enquiry through multiple channels is advisable.

Xuzhou Yutai Aluminum Manufacturing Co., Ltd. operates from Tang Zhang Industrial Park, Xuzhou 221000, Tongshan District, Jiangsu Province, China. The company is classified as an imported-tier supplier with harbour trust tier designation. Their registered address places them within Xuzhou's industrial zone, approximately 260 km northwest of Shanghai port, potentially offering logistical advantages for inland manufacturing with coastal export. The listing provides no information about establishment date, number of employees, annual turnover, or production floor area. The company name references aluminium manufacturing, yet this specific listing covers copper alloy products, suggesting either diversified production or a broader metals portfolio than the company name indicates.

The supplier shows a 0.00% response rate with zero average response hours, indicating no platform-mediated buyer communication history. No quality management certifications (such as ISO 9001), material test reports, or customer references are present in the source data. The product description contains detailed dimensional and alloy specifications, suggesting technical competence in metals specification, though buyers should independently verify actual production capability through factory audit or video facility tour. The mention of multiple alloy systems (phosphor bronze, imitation-gold copper, nickel-silicon-chromium copper) implies some breadth in non-ferrous rolling capability, but confirmation of actual equipment (reversing mill, continuous casting, annealing furnaces) is essential before committing to volume orders.
