Metal Foil represents ultra-thin rolled metal materials engineered for critical industrial, thermal, electrical, and packaging applications. Produced with extreme gauge precision and clean surface finishes, metal foils deliver superior barrier protection against light, moisture, gases, and electromagnetic interference while maintaining excellent formability and high thermal/electrical conductivity.

As a leading factory-direct supplier, XQJ Metal (xqjmetal.com) manufactures and supplies a comprehensive inventory of high-performance metal foils—including aluminum foil, copper foil, stainless steel foil, and custom alloy foils. Tailored for automated manufacturing, transformer winding, lithium-ion battery current collectors, flexible packaging, and pharmaceutical blister packs, our foil products strictly comply with international quality standards (ASTM, EN, ISO).

Popular Metal Foil Categories & Materials:

• Aluminum Foil: Supplied in 1000, 3000, and 8000 series alloys (e.g., 8011, 8079, 1235). Essential for food packaging, pharmaceutical blisters, air conditioner fins, cable shielding, and industrial insulation.

• Copper Foil: High-purity electrodeposited (ED) and rolled-annealed (RA) copper foil providing high electrical conductivity. Widely used in printed circuit boards (PCBs), lithium-ion battery anodes, and electromagnetic shielding.

• Stainless Steel Foil: Ultra-thin precision stainless steel foil (304, 316L, 430) offering high heat resistance, chemical durability, and spring temper. Applied in catalytic converters, solar panels, sensors, and aerospace gaskets.

• Battery & Shielding Foil: Specialized ultra-thin foils designed for high-density energy storage, transformer coil insulation, and flexible electronic components.

Frequently Asked Questions (FAQ):

Q: What types of metal foils does XQJ Metal supply?

A: We manufacture and distribute a broad range of industrial and packaging metal foils, focusing primarily on high-purity aluminum foils (such as 8011, 8079, and 1235 alloys), copper foils for electronics and batteries, and ultra-thin stainless steel foils.

Q: Can XQJ Metal provide custom slitting, roll sizing, and core options?

A: Yes, we operate high-precision slitting equipment capable of trimming jumbo foil coils into custom narrow widths starting from 50 mm, with precise edge quality and custom paper, aluminum, or steel cores.

Q: Do you provide Mill Test Certificates (MTC) and food-grade/environmental compliance reports?

A: Yes, every XQJ Metal foil shipment includes official EN 10204 3.1 Mill Test Certificates detailing chemical composition and mechanical properties, as well as FDA, EU, and RoHS compliance certificates where required.

Q: What is the MOQ and standard delivery lead time for wholesale metal foil orders?

A: Our standard MOQ ranges from 500 kg to 2 metric tons depending on the material, thickness, and alloy grade. Standard lead time for standard stock coils is 7–10 business days, while custom slitted or special alloy orders typically take 12–18 business days.
