You may return most new, unopened items within 7 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.

Precision-engineered MoSi₂ heating elements for demanding high-temperature applications
At elevated temperatures in oxidizing environments, MoSi₂ elements form a dense SiO₂ (quartz) protective layer that acts as a self-healing barrier against further oxidation. This unique property extends element lifespan significantly.
Maximum safe operating temperatures vary based on furnace atmosphere. Select the appropriate element type for your application:
| Atmosphere Type | BR1700 Series (Working temp: 1600°C) |
BR1800 Series (Working temp: 1700°C) |
Performance Rating |
|---|---|---|---|
| Air | 1700°C | 1800°C | Optimal |
| Inert Gas (He / Ar / Ne) | 1650°C | 1750°C | Excellent |
| SO₂ | 1600°C | 1700°C | Good |
| CO / N₂ | 1500°C | 1600°C | Moderate |
| Wet Hydrogen | 1400°C | 1500°C | Limited |
| Dry Hydrogen | 1350°C | 1450°C | Restricted |
Industry-leading performance backed by advanced manufacturing technology
Unique auto-repair mechanism through SiO₂ layer regeneration. Unlike conventional heating elements, our MoSi₂ elements automatically form a protective oxide layer that shields against oxidation damage, even after thermal cycling.
Heat-molded manufacturing process ensures consistent dimensions and structural integrity. Our advanced production line can create custom geometries and sizes to match your exact furnace specifications.
Proprietary joint molding technology with reinforced welding creates exceptional impact resistance. Our elements withstand thermal shock and mechanical stress far better than traditionally-manufactured alternatives.
High-density construction (5.8 g/cm³) with optimized electrical conductivity delivers rapid heating rates while minimizing power consumption. Achieves target temperature 25% faster than conventional elements.
Industry-exclusive compatibility feature allows new and aged elements to operate together seamlessly. Our standardized resistance profiles ensure balanced heating even with mixed-age installations.
Engineered for 24/7 industrial operation in oxygen-rich atmospheres. Stable performance across the entire temperature range with minimal degradation over time.
Our MoSi₂ elements feature standardized resistance profiles that allow new and used elements to work together harmoniously. This means you can replace individual failed elements without purchasing complete sets—a feature virtually unmatched in the industry.
Real-world impact: A typical 6-element furnace requiring one replacement saves $800-1,200 per incident compared to full-set replacement. Over a furnace's lifetime, this flexibility saves thousands in maintenance costs.
Follow these critical procedures to ensure optimal performance and maximum element lifespan
Before beginning installation: Ensure power is completely disconnected. Verify furnace is at ambient temperature. Wear appropriate PPE including heat-resistant gloves and safety glasses. MoSi₂ elements are brittle at room temperature—handle with extreme care to prevent breakage.
MoSi₂ exhibits dramatically different properties at different temperatures:
Vertical suspension eliminates direct mechanical stress on the heating zone. If mounted horizontally or at angles, thermal expansion and gravitational forces cause premature fracture at hot spots.
1. Position element holder at designated furnace roof location
2. Lower element through roof opening until heating zone is fully inside chamber
3. Secure element in holder—finger-tight only at this stage
4. Verify element hangs freely without touching furnace walls
5. Check vertical alignment with plumb line or level
Important: Do NOT fully tighten the retaining strap during cold installation. The element needs room to expand as it heats up and transitions to its plastic state.
The wire clip conducts current to the element and must be carefully managed to prevent overheating:
Maintain at least 50mm clearance between the lower edge of the wire clip and the top surface of the refractory brick. This prevents radiant heat from the furnace chamber from degrading the electrical connection.
Operating beyond recommended current limits causes excessive heat generation and premature failure:
Use only aluminum braid strap or multi-layer aluminum foil as specified:
Element End: The strap wraps around the cold end of the MoSi₂ element above the furnace roof
Bus Bar End: Strap connects to main power bus bar using mechanical clamp
Important: The external clamp/fastener is for mechanical retention only—NOT for electrical conduction. Current flows through the aluminum braid/foil material.
Strap length should be 10-15% longer than the straight-line distance between element and bus bar. This extra length provides:
