Nichrome 30/20 Resistance Strip
Heanjia Super-metals Co., Ltd. supplies Nichrome 30/20 Resistance Strip. Nichrome 30/20 Resistance Strip is a nickel-chromium-iron resistance alloy with heat resisting strength at high temperatures. This alloy is also used in numerous domestic appliances and industrial resistors. Nichrome 30/20 Resistance Strip has relatively high resistivity and very good resistance to oxidation at high temperatures. Nichrome 30/20 Resistance Strip is used in industrial furnaces (up to 1050°C), heating elements of cooking equipment.

Applications
1. Heating Elements
Manufacturers mainly use nichrome Strip to make coils for heating elements.
2. Hot-Strip Cutter
It cuts through materials like polystyrene foam, somewhat like a Strip cheese cutter. The heat does the cutting, and makes a smoother and more even cut than a saw or knife could achieve.
3. High-Temperatures Uses
Because of nichrome Strip's strength at extremely high temperatures and its flexibility, pottery enthusiasts use it to assemble backyard kilns and to hold the shape of pottery items while they bake.
4. Igniters
Nichrome Strip heats up rapidly with even a small amount of electricity; it makes safe igniters (sometimes called electric matches) to light the fuses of fireworks and model rockets.
Manufacture Process
The manufacture of strip is started with producing the ingot by advanced vacuum melting process. The trip production includes forging, rolling, annealing, acid-washing, polishing, cutting etc. The strip is produced to the required sizes. From the ingot to the final strip, manufacture process is operated with high standard quality control system. There will be quality test for each batch of product, such as test to thickness tolerance, content, hardness, etc.
Packing Process & Transportation
Packaging: Seal up, with plastic inside and wooden case or carton outside; or according to the customer's requirements.
Transportation: By air or By sea
