High-Temperature Ultra-Dense Tungsten Rods
- Maximum Temperature: 2,300° F
- Yield Strength: Not Rated
- Hardness: Rockwell C35 (Hard)
- Temper Rating: Not Rated
Ultra dense for use as electrodes, furnace support pillars, and screws and bolts, these chemically pure tungsten rods withstand greater heat than other high-temperature metal, such as molybdenum. You can also use them in applications where voltage increases may cause temperature spikes that other metal can’t handle. These rods won’t deform in high heat, so they last longer than other metal. However, they’re harder to machine than more ductile tungsten alloys. These rods won’t corrode from chemicals or weather.

Platinum Wire
- Hardness: Rockwell B97 (Medium)
Use this 99.95% pure platinum wire to create thermocouple probes and other parts that maintain high accuracy in extreme conditions. It won’t oxidize, won’t corrode in most settings, and has low thermal and electrical resistance. Platinum is often used to make O-rings, even for high-vacuum applications, because it’s soft enough to form a good seal when pressed between two flanges, yet won’t damage the flanges so you can reuse them. It’s also useful with high temperatures since it has a higher melting point than other sealing materials, such as gold.

Tantalum Wire
- Hardness: Rockwell C69 (Ultra Hard)
Harder than platinum and able to withstand higher temperatures than gold, this 99.98% pure tantalum wire also resists corrosion and conducts heat. It’s often used in heating elements for furnaces.
