Purpose and applications

The gold semi-finished product is intended for professional technological and research work. It is selected based on product type, geometry, metal grade, reference document, and requirements for further processing. The specific application of a part is determined by the project documentation.

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 specify working dimensions, tolerances, delivery condition, flatness or straightness requirements, and the permissible processing method. 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 cutting, forming, and installing, it is important to preserve the material surface and avoid foreign inclusions. The tool and processing mode are selected based on the product geometry and delivery condition. Tolerances after additional processing must be considered when ordering the blank.

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 GOST or TU reference in the name does not replace the approval of the specific configuration.
