Tolerances, delivery condition, length, packaging, and batch size must be agreed upon before ordering.

Purpose and applications

Gold wire is used as a semi-finished product for contact, connection, and research tasks. Suitability for drawing, forming, welding, or assembly depends on the diameter, metal grade, delivery condition, and surface requirements. The specified size must be matched with the equipment and design.

How to select the configuration

The main selection parameters are already listed in the product card: product type, size or thickness, gold grade, and reference document. Additionally, you should determine the working dimensions, tolerances, delivery condition, flatness or straightness requirements, and acceptable processing methods. Grades with similar designations cannot be considered interchangeable without verifying composition and documentation. This item specifies grade Au 99.9; the acceptability of this gold and impurity content should be confirmed against project requirements.

Working with the material

When working with the wire, control the bend radius, tension, and surface condition to avoid localized thinning or mechanical damage. For precise operations, tooling cleanliness and geometric stability along the length are important. Acceptable thermal or mechanical processing should be agreed upon according to the delivery documents.

Quality control

For incoming inspection, compare the marking and actual geometry with the order, check surface integrity, and verify the completeness of accompanying documents. The content of the base metal, impurities, and the test method must be confirmed by the batch passport or certificate. The mention of GOST or TU in the name does not replace the agreement of the specific configuration.
