Whether you're a jeweler, electronics hobbyist, or fabrication maker, these 1mm thick T2 copper round plate blanks give you a ready-to-use starting point — no cutting, no guesswork.\u003c\/p\u003e\n\u003cp\u003eEach disc is cut from T2-grade copper flat stock, offering a thickness of 1mm (approx. 0.039 in) and a diameter of 87mm (approx. 3.43 in). T2 copper is a commercially pure copper grade with copper content typically ≥99.9%, known for its excellent electrical conductivity, thermal performance, and workability. The surface is smooth and uncoated, suitable for further machining, stamping, or finishing.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include copper disc anodes for electroplating setups, heat spreader blanks for DIY thermal management, custom jewelry and pendant blanks for metalsmithing, grounding pads and bus bar blanks for electrical enclosures, and decorative inlay or craft discs for woodworking and mixed-media projects.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for general metalworking, jewelry making, electronics fabrication, and thermal management applications.
