Forms and applications

Thulium metal, alloys and compounds are used in specialized optical, electronic and research applications. Material form and suitability depend on purity, impurity limits, processing route and the purchaser's specification; an element name alone is not an acceptance standard.

U.S. sourcing overview

Thulium, chemical symbol Tm and atomic number 69, is a rare-earth element used in specialized optical, electronic, research and alloy applications. A purchasing request should identify the material as thulium, not the legacy misspelling "tulium," and state whether the requirement is for elemental metal, an alloy, a compound or a fabricated product.

Product forms and sourcing

Sourcing can be reviewed for ingot, pieces, granules, powder, foil, sheet, wire and purchaser-specified forms, subject to purity, dimensions and quantity. State the required thulium content, impurity limits, form, size, surface condition, packaging and any restrictions on production route or country of origin.

Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, production route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.

Specification and substitution

Rare-earth products sold under the same element name can differ in purity basis, oxygen and other interstitial limits, particle size, processing route and analytical method. The quotation must be checked against the purchaser's specification and intended process before an order is approved.

The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.

Information required for a quote
