1.3mm sheet aluminium mirror

When sourcing 1.3mm aluminium mirrors, the reflectivity rate is the most critical factor; high-quality sheets should offer at least 86% to 95% reflectivity. Ensure the base material is a high-purity aluminium alloy (typically 1060, 1070, or 1085) to prevent oxidation. The surface treatment should be either anodized or vacuum-coated to ensure a smooth, ripple-free finish. Additionally, verify the thickness tolerance, which for a 1.3mm specification should ideally be within ±0.02mm to ensure compatibility with precision frames or lighting fixtures.

The 1.3mm thickness is a 'sweet spot' for lightweight yet rigid applications. It is primarily used in lighting reflectors (LED high bays, parabolic louvers), solar concentrators, and architectural decorative panels. It is also widely adopted in the consumer electronics industry for laptop or smartphone internal shielding and decorative trims. Because it is thinner than standard 2mm glass mirrors, it is ideal for weight-sensitive projects like RV interiors or aerospace cabin trim.

Buyers should demand Salt Spray Test reports (usually 48h to 96h) to ensure corrosion resistance, especially if the product is used in humid environments. Compliance with RoHS and REACH standards is mandatory for entry into the EU and US markets to ensure no hazardous substances are present in the coating. For architectural use, check for Class A fire ratings. Always request a protective film (PE or Blue film) on the mirror side to prevent scratching during fabrication and transport.

Since 1.3mm aluminium is highly malleable, confirm if the supplier can perform precision die-cutting, CNC punching, or laser cutting without cracking the mirror surface. Ask if the material supports deep drawing or bending; high-quality mirror sheets should allow for a minimum bending radius without 'orange peel' effects or coating delamination. If your project requires specific shapes, sourcing from a supplier on Made-in-China.com who offers OEM/ODM fabrication services can significantly reduce your secondary processing costs.

Aluminium mirrors are highly sensitive to scratches and oxidation. You must insist on seaworthy packaging, which includes double-sided protective films, desiccant silica gel packs to prevent moisture spots (white rust), and fumigated wooden crates with reinforced steel strapping. For LCL (Less than Container Load) shipments, ensure the crates are top-load only to prevent crushing.

Aluminium pricing is tied to the LME (London Metal Exchange) spot price. Negotiate a formula-based pricing model (LME base price + fabrication premium) rather than a fixed price to ensure fairness during market fluctuations. For orders exceeding 5 tons, you should aim for a 5-8% discount on the fabrication premium. Always clarify if the quoted price includes the export tax rebate, which can impact the final invoice significantly.

Utilize the Secured Trading services on Made-in-China.com to protect your payment until the goods are shipped. Before placing a large order, hire a third-party inspection agency (like SGS or Intertek) to perform a 'During Production Check' (DUPRO) and a 'Final Random Inspection' (FRI) to verify that the reflectivity and thickness meet your specific requirements.

Be aware of Anti-dumping (AD) and Countervailing Duties (CVD). Some countries impose high tariffs on Chinese aluminium products. Check your local customs tariff schedule using the HS Code (typically 7606.11 or 7606.12). To navigate this, work with experienced exporters on Made-in-China.com who can provide a Certificate of Origin and help determine the most cost-effective shipping Incoterms, such as CIF for convenience or FOB for better freight control.
