Electromagnetic Induction Heating Coil Kit – Copper Coils for High-Frequency Heating Applications This induction coil kit includes seven commonly used pre-formed coils in various diameters, plus one additional free coil, providing versatility for a wide range of heating tasks. The set includes: 4 x 18mm internal diameter coils, 1 x 22mm internal diameter coil, 1 x 28mm internal diameter coil, and 1 free-form coil measuring 100cm in length. Each coil is constructed from high-quality copper, offering excellent resistance to overheating and premature wear. Designed for durability, these coils can withstand repeated use over hundreds of cycles. The flexible design allows easy bending to achieve the desired shape for specific applications. The coils are electroplated to prevent oxidation and ensure consistent electrical contact, enhancing overall performance and efficiency. Insulated winding protects against accidental contact, and the protective coating helps resist wear during operation. If insulation becomes damaged, replacement is recommended for safe operation. Material: Copper Dimensions: - Free-form coil: 100cm long - Pre-formed coils: 21 x 3cm (inner diameter: 1.8cm), 21 x 3.5cm (inner diameter: 2.2cm), 21 x 4cm (inner diameter: 2.8cm) Package Includes: 4 x Heating Coils
