Product Description
Spiral Electric Resistor NiCr Alloy for Air Conditioner Heating
This spiral electric resistor utilizes NiCr (Nickel-Chromium) alloy construction with resistance values ranging from 1 to 5 Mohm, specifically engineered for air conditioner heating elements requiring stable thermal performance and durability.
Material Specifications
The resistor employs Constantan alloy, a copper-nickel composition (typically 55% copper, 45% nickel) known for its stable resistivity across wide temperature ranges. This material is also referred to as Eureka, Advance, and Ferry in various industrial applications.
Key Features
- Stable resistivity across temperature variations
- High ductility for complex forming requirements
- Non-magnetic austenitic structure
- Resistance range: 1-5 Mohm
- Designed for air conditioner heating applications
