Import Aluminum Casting Alloys Chart — Buy in wholesale FOB from Supplier in China

Hebei Rongxing Driving Equipment Technology Co., Ltd. offers aluminum casting alloys grades ADC12, A383 and A380 for die casting and sand casting of industrial machinery and automotive components. These alloys are supplied in standard ingot form with chemistry conforming to recognised international specifications. The ADC12 grade contains nominally 9.6 to 12 percent silicon, 1.5 to 3.5 percent copper, 0.5 to 1.3 percent iron, 0.1 to 0.5 percent magnesium, 0.1 to 1.0 percent zinc, 0.1 to 0.5 percent nickel and maximum 0.1 percent tin. A380 offers similar silicon and copper ranges with tighter iron limits, making it the default choice for engine blocks and transmission cases where higher strength is required.

The fluidity of these hypoeutectic Al-Si-Cu alloys derives from their silicon content, which controls feeding distance and reduces hot tearing in thin sections. ADC12, equivalent to Japanese JIS H 5302:2000 alloy, is the workhorse grade for general purpose die casting in Asia, while A383 (ANSI/AA designation) offers marginally better corrosion resistance and is preferred for decorative or coastal applications. Both grades accept standard heat treatment: T5 temper for stress relief after casting, or T6 for maximum mechanical properties. Typical as-cast tensile strength is 228 to 310 MPa depending on wall thickness and cooling rate, with elongation of 2.5 to 3.5 percent in separately cast test bars.

Buyers in automotive, power-tool and general-engineering sectors use these alloys for transmission housings, pump bodies, valve covers, bracketry and motor frames. The ingots are typically shipped in bundles of 20 to 25 kg, strapped on wooden pallets for container loading. Standard lot sizes for export from Hebei are 1 to 25 metric tons, though the exact minimum order quantity should be confirmed directly with the supplier. The supplier's facility is located in Hengshui City, Hebei Province, an industrial corridor with established logistics links to Tianjin Port for seafreight export.

Hebei Rongxing Driving Equipment Technology Co., Ltd. is located on the north side of Planning 4th Road, Southern Industrial New Town, Jizhou District, Hengshui City, Hebei Province, China. The supplier holds a harbor trust tier designation on this platform, with a response rate currently showing 0.00 percent and an average response time of zero hours, which indicates no inquiry activity has been recorded or the supplier has not yet engaged with buyers through the platform messaging system. Buyers should therefore initiate contact through multiple channels and verify responsiveness before committing to orders.

The company lists product categories spanning couplings and casting alloys, suggesting a diversified manufacturing or trading operation serving industrial machinery and automotive supply chains. No verified factory size, annual turnover, employee count, or specific certifications are stated in the available profile data. Buyers are advised to request a current business licence, ISO 9001 certificate if claimed, and alloy composition test reports (spectrometry) before placing purchase orders. Direct factory audit or third-party inspection is recommended given the absence of verified trade history on this listing.
