Import Brass Casting — Buy in wholesale FOB from Supplier in China

Brass casting from Shandong Speed Steel Seiko Factory Co., Ltd. is a copper-zinc alloy casting process yielding components for demanding industrial environments. The material draws from brass grades C21000 and C22000, with typical composition spanning 90-95% copper and 5-10% zinc alongside trace lead content. The source indicates brass's narrow crystallization temperature interval grants superior casting properties versus tin bronze alternatives, enabling complex geometries with reduced porosity risk. Shandong Speed Steel Seiko Factory operates from Jiulong Street Industrial Park in Jiaozhou City, Qingdao, within China's established Shandong Province metalworking corridor.

The factory's brass castings leverage the material's inherent machinability and golden-yellow appearance for applications requiring both functional performance and aesthetic finish. Standard industry practice allows elemental additions to create special brass variants suited to corrosive or high-wear environments, though specific alloy modifications for this supplier's output require direct confirmation. Cast brass generally exhibits better mechanical properties than cast tin bronze, with zinc content reducing raw material costs though potentially compromising corrosion resistance in certain media. Buyers typically specify heat treatment, surface finish, and dimensional tolerances according to end-use requirements in automotive, plumbing, marine, and electrical sectors.

This product category serves OEM manufacturers, industrial valve producers, custom hardware fabricators, and marine equipment suppliers seeking reliable copper alloy components. The supplier's harbor-tier trust classification indicates baseline marketplace standing, though buyers should note the current 0.00% response rate and verify active communication channels before committing to orders. Typical procurement involves confirming exact grade specification, mechanical property requirements, and any secondary machining needs. International buyers commonly negotiate Incoterms around Qingdao port shipment, with standard packaging for brass castings typically involving moisture-resistant wrapping and wooden crating for ocean freight protection.

Shandong Speed Steel Seiko Factory Co., Ltd. is based at Jiulong Street Industrial Park in Jiaozhou City, Qingdao, within Shandong Province, a region with substantial concentration of metalworking and foundry operations. The supplier holds a harbor-tier trust classification, representing a baseline verification level within marketplace systems. The company profile does not disclose establishment year, employee count, annual revenue, or specific production capacity figures. Buyers should request these operational details directly to assess scale compatibility with their volume requirements. The supplier's current response metrics show 0.00% response rate with zero average response hours recorded, indicating potential communication challenges that merit proactive verification before order commitment.

The listing presents brass casting as a core product line with emphasis on standard grades C21000 and C22000, suggesting familiarity with conventional copper alloy specifications rather than specialized or proprietary formulations. No customer references, certification listings, or export experience documentation appears in the available profile data. The industrial park location in Qingdao provides proximity to major port infrastructure, a logistical advantage for international shipment, though specific export capabilities and documentation support require direct confirmation. Buyers evaluating this supplier should prioritize verification of quality management systems, sample provision protocols, and engineering communication capacity given the custom nature of casting projects.
