What is Furnace Contact Clamp?
Furnace contact clamps are conductive parts of industrial furnaces, mainly used for clamping. Due to the special working environment of furnace, the contact clamp should be resistant to high temperature and strong magnetic fields.
Furnace contact clamps are mainly used on:
- Industrial Electric Furnace
- Electric Arc Furnace (EAF)
- Submerged Arc Furnace (SAF)
- Heat Treatment Furnace

Material for Contact Clamps
Forging copper materials:
1. Copper forging (first choice for conductivity)
Grades: T2 / C11000 / Cu-ETP
Advantages: Excellent conductivity≥98% IACS, no air holes
Recommended applications: water cooling electrode clamp, heavy high-power electric arc furnace
2. Chromium-copper forging (high temperature, high strength)
Grades: QCr0.5 / C18200 / CW105C
Advantages: High strength, good conductivity 80% IACS
Recommended applications: Long-term high-temperature electrode clamp
3. Chromium-Zirconium Copper Forging (highest-end application)
Grades: QCr1-0.15 / C18150 / CW106C
Advantages: Balanced conductivity, high temperature resistance, and creep resistance
Recommended applications: high-end furnace, heavy-duty furnace contact clamp
4. Tellurium copper forging (good machineability and high conductivity)
Grade: C14500
Advantages: High conductivity, easy for machining, ensuring high precision contact surfaces
Recommended application: high precision contact clamp
Casting copper materials:
1. Chromium-Zirconium Copper Casting (as-cast conductivity)
Grade: ZCuCrZr / C86300
Advantages: Good castability, ideal for complex contact clamp, stable conductivity
Recommended application: medium-load contact clamp, one-piece formed contact clamp
2. Aluminum bronze casting (strong wear resistance)
Grade: ZCuAl10Fe3 / C95400
Advantages: high strength, wear resistance, thermal shock resistance
Recommended application: heavy-load impurity clamps
3. Tin bronze casting (wear resistance and corrosion resistance)
Grade: ZCuSn10Pb1 / C90700
Advantages: self-lubrication, corrosion resistance, stable sizes
Recommended application: lower current, wear resistant positioning clamp
4. Brass casting (cost-effective)
Grade: ZCuZn38 / C28000
Advantages: low price, easy for casting and machining
Recommended application: general furnace structural clamp
Fast material selection for furnace contact clamp:
High-end conductivity → Forged chromium-zirconium copper C18150
Extremely conductivity → Forged copper T2/C11000
Complex structure → Cast chromium-zirconium copper / Cast aluminum-bronze
Cost-effective → Cast brass / Cast tin bronze
