Import Aluminum Substrate Al Ccl Mcpcb Sheet — Buy in wholesale FOB from Supplier in Global Markets

Aluminum substrate AL CCL MCPCB sheet from Wuxi Chifeng Metal Products Co., Ltd is a metal-core printed circuit board material comprising an aluminium base, thermally conductive dielectric layer, and copper foil cladding. The standard panel size measures 1000 by 1200 millimetres (40 by 48 inches), with overall board thickness ranging from 0.4 millimetres to 4.0 millimetres in graded increments. Copper foil options include 18 micrometres, 25 micrometres, 35 micrometres, and 70 micrometres, accommodating single-sided circuit designs. Thermal conductivity ratings span 0.5, 1.0, 1.5, and 2.0 watts per metre-kelvin, allowing engineers to match material performance to LED thermal management requirements.

The aluminium core provides mechanical rigidity and heat-spreading capability that standard FR-4 laminates cannot match. The dielectric layer between aluminium and copper must achieve both electrical isolation and thermal conduction, typically using epoxy or polyimide filled with ceramic particles such as aluminium oxide or aluminium nitride. Chifeng offers boards with blue or green protective film, or bare finish without film, depending on downstream processing needs. The material grade and surface finish should be selected based on the operating temperature range and thermal cycling demands of the end application.

This MCPCB material targets LED lighting manufacturers, power electronics fabricators, and automotive electronics suppliers who require effective thermal dissipation in compact form factors. Applications include LED lamp modules, power supply boards, audio equipment amplifiers, and electromagnetic shielding assemblies. Buyers should confirm copper weight tolerance, dielectric breakdown voltage, and peel strength with the supplier before committing to volume orders. Standard lead times and MOQ are not stated in the listing and must be negotiated directly with Wuxi Chifeng Metal Products.

Wuxi Chifeng Metal Products Co., Ltd maintains its registered office at Saige Mansion on Huishan Main Road in Wuxi City, Jiangsu Province, China, postal code 214000. The supplier holds a harbour trust tier designation on the platform, with a response rate shown as 0.00 percent and no recorded average response time. These signals suggest limited or no engagement through platform messaging, so buyers should expect to initiate contact through alternative channels and allow additional time for quotation and sample requests.

The company lists its brand name as Chifeng on product materials and focuses on aluminium copper-clad laminates with complete specification series. No information is provided about factory size, year of establishment, annual revenue, export licence status, or named client references. Buyers should request company registration documents, ISO certification copies, and past export records during initial due diligence. The product range centres on LED thermal management substrates rather than general PCB fabrication services.
