About Wuxi Xihai Foundry - Metal Castings & Forgings Supplier in China

Wuxi Xihai Foundry is based in China and lists five distinct metal‑casting products. The catalogue includes nonferrous metal castings labelled as precision metal, a second entry for precision metal casti, a line of nonferrous precision casting described as precision alloy ca, aluminum alloy castings identified with the suffix “30”, and filter castings such as cast filter head and cast head. All items fall under the broader HS‑80 chapter for cast metal products, which is used for customs classification of iron, steel and non‑ferrous castings. The supplier is classified as an imported tier with a harbor trust rating, indicating that it operates through established trade channels.

The five catalogue entries cover typical product families that buyers source for automotive, machinery and industrial filtration applications. Non‑ferrous precision castings are commonly produced from copper‑zinc, bronze or nickel‑based alloys, while aluminum alloy castings are usually supplied in grades such as AlSi12 or AlSi7Mg. Filter castings are often fabricated from stainless‑steel or high‑grade aluminum to meet corrosion‑resistant requirements. Buyers encountering these listings should reference the HS‑80.20 to HS‑80.99 sub‑headings that correspond to non‑ferrous alloy castings and related components.

Product Range and Specialties of Wuxi Xihai Foundry

The catalogue lists nonferrous metal castings labelled as precision metal, a second similar entry, a precision alloy casting line, aluminum alloy castings and filter‑head castings. In the nonferrous sector, typical grades include CuZn37 (brass), CuSn10 (bronze) and nickel‑based alloys such as Ni‑201, each commonly supplied to tolerances of ±0.05 mm for critical dimensions. Aluminum alloy castings are frequently produced in alloys AlSi12, AlSi7Mg or 380.0, with surface roughness (Ra) usually specified between 0.8 µm and 1.2 µm for machining‑ready parts. Filter castings for industrial filtration are often made from AISI 304/316 stainless steel or high‑strength aluminum, and are tested for pressure‑drop performance and dimensional conformity to ISO 1083 standards. Buyers should expect product data sheets that list chemical composition, mechanical properties (e.g., tensile strength 250‑350 MPa for typical bronze alloys) and casting defects limits such as porosity below 0.5 % by volume.

Trade and Export Information - Wuxi Xihai Foundry

China is a leading exporter of metal castings, with the majority of shipments classified under HS‑80.20 (aluminum alloy castings) and HS‑80.30 (non‑ferrous alloy castings). Typical destination regions include the European Union, North America and Southeast Asia, where automotive, aerospace and heavy‑machinery manufacturers source precision components. Export documentation frequently requires a commercial invoice, packing list, certificate of origin and, where applicable, an ISO 9001 or ISO/TS 16949 compliance certificate. Buyers often request a pre‑shipment inspection under the China Inspection & Certification (CIQ) regime, especially for high‑value aerospace parts. Standard logistics involve containerised loads on 20‑ft or 40‑ft containers, with FOB or CIF terms negotiated based on the buyer’s location.

Sourcing from Wuxi Xihai Foundry - Buyer Guidance

When sourcing from Wuxi Xihai Foundry, buyers should request a recent material test report (MTR) that confirms chemical composition against ASTM B584 for copper alloys or ASTM B209 for aluminum alloys. A dimensional inspection report aligned with ISO 2768‑m tolerance grades (fine or medium) helps verify that the precision castings meet the required specification. If the buyer’s market requires it, ask for a copy of the supplier’s ISO 9001 certification and any industry‑specific quality system certificates, such as IATF 16949 for automotive parts. Samples are typically supplied in wooden crates or on pallets, with protective padding to avoid impact damage during sea freight. Verify the packaging dimensions and weight to calculate container utilization before confirming the order.

What types of metal castings does Wuxi Xihai Foundry list in its catalogue?

The catalogue includes five entries: nonferrous metal castings labelled as precision metal, a second precision metal entry, nonferrous precision casting described as precision alloy ca, aluminum alloy castings identified with “30”, and filter castings such as cast filter head and cast head.

Which HS‑code chapters apply to the listed products?

All listed items fall under HS Chapter 80, which covers cast metal products. Specific sub‑headings are typically HS‑80.20 for aluminum alloy castings and HS‑80.30 for non‑ferrous alloy castings.

What industry standards are commonly used for these castings?

Typical standards include ASTM B584 for copper‑based alloys, ASTM B209 for aluminum alloys, ISO 1083 for casting tolerances, and ISO 2768‑m for geometric tolerances.

What certifications should a buyer request from this supplier?

Buyers should request the supplier’s ISO 9001 certificate and, for automotive applications, an IATF 16949 or ISO/TS 16949 compliance document if available. Additional material test reports should be requested for each alloy.

What are the usual packaging methods for metal castings from China?

Metal castings are normally packed in wooden crates or on standard pallets, with internal cushioning (foam or wood blocks) to prevent impact. Containers are loaded as 20‑ft or 40‑ft units depending on volume.

What are typical lead times and minimum order quantities for non‑ferrous precision castings?

Lead times generally range from four to eight weeks after order confirmation, depending on the complexity of the casting. Minimum order quantities are often expressed in weight, commonly 500 kg to 1 ton per alloy grade, but exact figures should be confirmed with the supplier.

How can a buyer arrange a sample shipment?

A buyer can request a sample by specifying the alloy grade, dimensions and required certification documents. Samples are usually shipped by air freight on an FOB basis, with the cost borne by the buyer unless otherwise agreed.

Which markets typically import these types of castings?

Key import markets include the European Union (Germany, Italy, France), the United States, Japan, South Korea and emerging manufacturers in Southeast Asia such as Vietnam and Thailand, where the castings are used in automotive, aerospace and industrial equipment production.
