Import Aluminium Strontium Alloy — Buy in Bulk from Supplier in China

Aluminium strontium alloy from Sino Dongfeng Wealth Holdings Ltd. is a casting modifier designed to refine grain structure in aluminium-silicon alloys, improving mechanical properties like tensile strength and elongation. The supplier’s material is positioned for industrial use where lightweight, corrosion-resistant components are required, with a focus on automotive and aerospace applications. The alloy’s primary function is to modify eutectic silicon morphology, reducing shrinkage and hot tearing during casting.

The material combines aluminium as the base metal with strontium as the active modifier, typically added at ppm levels to achieve the desired metallurgical effect. Standard industry practice for such alloys includes strontium content in the 0.01 to 0.05% range, which enhances fluidity and reduces porosity in the final cast. The alloy is compatible with common aluminium casting processes, including sand, permanent mold, and die casting, and is supplied in ingot or master alloy form for easy integration into foundry operations.

Manufacturers in the automotive sector use this alloy for engine blocks, cylinder heads, and transmission housings, while aerospace applications include structural components and brackets. The material’s ability to improve machinability and surface finish makes it a preferred choice for precision parts. Buyers should confirm the exact strontium concentration, packaging, and compliance with ASTM or ISO standards for aluminium alloys before ordering. Trade terms such as MOQ, incoterms, and lead time are available on request from the supplier.

Sino Dongfeng Wealth Holdings Ltd. is based in Shenmu, Yulin, Shaanxi, China, and operates as an imported-tier supplier with a harbor trust tier. The company’s profile indicates a focus on industrial materials, including specialty alloys, and serves buyers seeking export-quality products for manufacturing and construction sectors.

The supplier’s response rate is currently unrecorded, and no average response time is available, which may require buyers to follow up directly for trade inquiries. The listing does not provide details on production capacity, certifications, or client references, so these should be confirmed during negotiations. The company’s address in Shaanxi places it in a region known for metallurgical and heavy industry.
