    Description

    99.99% gold for technical requirements

    Gold with a stated purity of 99.99% may be requested for electrical, research, electroplating or other technical uses. Purity alone is not a complete purchase specification. State whether the material is elemental Au, an alloy or a fabricated product and define permitted impurities, analytical method and any application-specific requirements.

    Form, dimensions and documentation

    Identify the required form, such as anode, strip, wire, mesh, sheet, foil, granule or purchaser-defined blank. Include dimensions, tolerances, surface, quantity, packaging, traceability and certificate requirements. For electroplating or electrical service, specify the process and acceptance criteria. For reference, elemental gold has the symbol Au, atomic number 79 and a melting point of approximately 1064.18 °C. Evek LLC will confirm the feasible form, origin, testing, minimum quantity and commercial terms during quotation.

    Reference values for elemental gold do not certify the purity, chemistry or condition of a delivered lot. The purchase specification and assay certificate control acceptance.

    Information needed for a quote

    Send the gold purity or approved grade, product form, dimensions, quantity, permitted impurities, analytical method, packaging, certificate needs and U.S. delivery ZIP code.

    Stock, production route, origin, minimum quantity, compliance, certification, price and final delivery are confirmed during quotation. Product descriptions and reference data are not stock or suitability guarantees.
