Triply/5-ply circles are specially designed for optimal conductivity and heat distribution during cooking. These circles are made by compressing three or five different metals together using advanced technology, resulting in a highly efficient cooking surface. The circles are then cut into blanks for use in high-quality cookware. With their superior heat conductivity, these circles ensure even cooking and consistent results every time. Upgrade your kitchen with cookware featuring triply/5-ply circles for a professional cooking experience.

PRODUCT FEATURES
PRODUCT CHARACTERISTICS OF 3PLY TRIPLY CIRCLE
Three-layer composite metal, performance upgrade
304/316L/430 stainless steel (outer layer) - provides excellent corrosion resistance and high temperature resistance, ensures food contact safety, and is suitable for induction cooker heating.
Aluminum/Copper (middle layer) - excellent thermal conductivity, achieves uniform heating, improves thermal efficiency, and reduces energy loss.
430 stainless steel (bottom layer, optional) - suitable for induction heating of induction cookers, improves heating speed and energy saving effect.
High thermal conductivity, high efficiency, energy saving and environmental protection
The thermal conductivity of the composite aluminum core is as high as 160 W/m·K, which is more than 5 times that of traditional stainless steel, significantly reducing cooking heating time and saving more than 30% energy.
The copper core solution provides faster thermal response and is suitable for high-end professional cookware and industrial heat-conducting components.
High strength and durability
Explosive welding or high temperature rolling combined technology makes the metal layers tightly bonded, not easy to delaminate or peel off, suitable for high-strength processing such as deep drawing, stretching, and stamping.
High temperature resistance up to 400°C, can be used for a long time without deformation or discoloration.
Environmentally friendly and healthy, in line with international food grade standards
