Define the filament before requesting a quote
A drawn tungsten wire, a formed coil and a finished lamp or device filament are different purchase items. State whether the need is straight wire, a preformed coil or a drawing-defined part. Provide wire diameter, coil outside diameter or mandrel, pitch, leg length, finish and packaging when relevant. Device performance depends on the complete design and operating environment.
Specification and documentation
ASTM F288 addresses specified tungsten wire for electron devices and lamps, but its covered types do not represent every filament design. Include the required wire type, applicable standard edition, drawing and inspection requirements; confirm conformance for the particular wire or finished part.
What to include in your RFQ
- Straight wire, coil or finished filament and tungsten wire type
- Wire diameter, coil geometry, legs, tolerances and packaging
- Quantity, device drawing, testing and certificate requirements
- U.S. destination ZIP code and requested schedule
