Scourer wire 0.13mm

The most critical factor is the material grade, typically Stainless Steel 410, 430, or 304. For 0.13mm wire, you must verify the tensile strength (usually between 600-900 N/mm²) to ensure it doesn't break during high-speed knitting or winding. Additionally, check the elongation rate and ensure the wire has a bright, clean surface finish free of oil and rust to prevent contamination of the final cleaning product.

Grade 410 is the most common for budget-friendly scourers due to its magnetic properties and hardness, while Grade 304 is preferred for high-end, rust-resistant applications. Ensure the wire complies with RoHS and REACH standards, especially if the final product is intended for kitchen use, to guarantee it is free from heavy metal contaminants like lead or cadmium.

For industrial production, precision winding is essential to prevent tangling. Specify the spool type (e.g., DIN125, DIN160, or DIN200) and the net weight per spool (commonly 2kg to 8kg). The wire must be continuously drawn without joints, as breaks in the wire can cause significant downtime in automatic scourer-making machines.

Request a Material Test Report (MTR) or a Mill Test Certificate (MTC) that details the chemical composition (Chromium and Nickel content). Conduct a salt spray test to evaluate corrosion resistance and a diameter tolerance check; for 0.13mm wire, the tolerance should strictly be within ±0.002mm to ensure consistency in the weight of the finished scourer.

The primary risk is surface oxidation (rusting) during maritime transport due to humidity. Ensure the supplier uses vacuum packaging or moisture-proof paper and includes silica gel desiccant inside the wooden crates. Another risk is material substitution (e.g., 201 grade labeled as 410); always use third-party inspection services like SGS or Intertek to verify the chemical grade before shipment.

Steel prices fluctuate with the global nickel and chromium markets, so it is wise to negotiate a formula-based pricing or lock in rates for a specific period. For bulk orders, aim for FOB (Free On Board) terms to maintain control over shipping costs. When sourcing via Made-in-China.com, prioritize Audited Suppliers who offer Trade Analysis reports to ensure they have the production capacity to meet your lead times.

Scourer wire is heavy but compact, making it ideal for Full Container Load (FCL) shipping to minimize the cost per ton. Check your local Anti-Dumping Duty (ADD) regulations, as some regions impose high tariffs on stainless steel products from specific countries. Ensure the HS Code (typically 7223.00) is correctly declared on the Bill of Lading to avoid customs delays and fines.

Always use secure payment methods and avoid direct transfers to private accounts. Utilize the escrow or payment protection services provided by Made-in-China.com to ensure funds are only released upon confirmation of shipping documents. Clearly define the quality claim period (usually 30-60 days after arrival) in the purchase contract to protect against latent defects.
