KEY FEATURES
Thermal mass decides the control
The thinner it is, the faster it heats and cools.
The smaller the cross-section, the lower the thermal mass and the faster the temperature control.
Low thermal mass
Low Thermal Mass
A thin section heats and cools quickly, holding the target temperature precisely.
Temperature uniformity
Temperature Uniformity
An even cross-section along the heating length reduces temperature variation across the whole source.
Low-contamination surface
Low Contamination
High-purity material and surface treatment keep impurities out of the organic film.
Melting points by material
Melting point °C. The higher the figure, the higher the temperature it withstands.
Why thermal mass matters
Organic materials decompose if overheated. Fast response is what keeps the target temperature within a narrow band.
Repeated use
Deposition and cooling repeat, so it is formed with no residual stress at the bends.

DESIGN PRECISION
Resistance set to the equipment
In a heater, cross-section and heating length are what distinguish the product.
In the same geometry, changing the cross-section and length changes the resistance and the heating rate.
Cross-section design
Cross-section and length are worked back from the target resistance and supply power.
Machined geometry
Bent to the mounting specification of the source.
Material selection
Tungsten where the highest temperature is needed, molybdenum where formability is.
We do not pick a specification, we develop it with you. (Give us the equipment dimensions and the target temperature and resistance, and we will work out the cross-section with you.)

HANDLING
Handling precautions
These apply to refractory metals in general. Service life depends heavily on how the parts are handled.
01
01
Do not touch the parts with bare hands after unpacking. Oil from fingerprints carbonizes at high temperature and becomes a contaminant.
02
02
The material is weak against impact and bending. Tungsten is brittle at room temperature and can crack if dropped.
03
03
Do not heat above 500°C in air; oxidation accelerates sharply. Always use the parts in a vacuum or an inert atmosphere.
04
04
Avoid rapid heating and cooling. On first use, we recommend pre-heating (aging) at low current.
05
05
Store indoors in a dry place and keep the moisture-barrier packaging intact.
