Tri-Ply Clad Disc — Stainless Steel + Aluminum + Stainless Steel Cookware Blank
MESCO tri-ply clad discs bond two outer layers of food-grade 304 stainless steel with a high-conductivity aluminum core, delivering even heat distribution, warp resistance, and lasting durability for premium cookware lines. Every layer — material grade and thickness — can be customized to your production requirements.
- Custom stainless steel grade, aluminum alloy, and per-layer thickness
- Induction, gas, electric, ceramic, and halogen compatible
- FDA / LFGB / EU 1935/2004 food-contact compliant
- OEM / ODM ready for cookware brands and manufacturers
Three-Layer Clad Construction
Each clad disc is a metallurgically bonded sandwich of stainless steel and aluminum, giving cookware manufacturers the best of both metals: stainless steel for corrosion resistance and induction compatibility, aluminum for fast, even heat transfer.
Top Layer
304 Stainless Steel
Food-grade cooking surface, 0.4–0.8 mm
Core
Aluminum (1060)
High-purity heat conductor, 1.5–3.0 mm
Bottom Layer
304 Stainless Steel
Induction-ready outer shell, 0.4–0.8 mm
Why Choose MESCO Tri-Ply Clad Discs
Even Heat Distribution
The aluminum core spreads heat quickly across the whole surface, eliminating hot spots and preventing scorching.
All-Cooktop Ready
The magnetic 304 outer layer works on gas, electric, induction, ceramic, and halogen cooktops.
Food-Safe & Corrosion Resistant
Non-reactive 304 stainless steel is certified to FDA, LFGB, and EU 1935/2004 standards.
Built for Deep Drawing
Uniform grain structure and bond strength ensure clean forming on your production line.
Warp-Free Performance
Balanced SS-Al-SS construction resists warping even under commercial-kitchen heat.
Full OEM / ODM Support
You specify grade, thickness, and diameter — we clad it to your exact specification.

Manufacturing Process
- Select stainless steel and high-purity aluminum coils to ASTM / EN standards
- Degrease, brush, and clean surfaces for defect-free bonding
- Stack and cold-roll layers for initial bonding
- Diffusion-weld in vacuum furnaces for full metallurgical fusion
- Anneal and precision-level for flatness tolerance
- Blank to diameter, deburr, and apply surface finish
- Ultrasonic bond testing, shear testing, and surface inspection
- Package and ship with full material certificates
Frequently Asked Questions
Can I customize the thickness of each layer?
Yes. You can independently specify the top stainless layer, the aluminum core, and the bottom stainless layer thickness.
Which stainless steel grades are available?
304 is standard. We also clad with 316, 316L, 430, and 443 to match your target market.
Are the discs induction-compatible?
Yes. The magnetic stainless steel outer layer works on all induction cooktops.
Do you provide samples before bulk orders?
Yes. Paid samples ship within 7–10 days and are refunded against your bulk order.
What is the minimum order quantity?
The standard MOQ is 500 pieces per specification, with trial orders available for new partners.
What is the typical lead time?
Standard specifications ship in 15–25 working days after order confirmation.
