Gold wire Zl 99.99 per TU 1866-353-05785324-2002

The item is confirmed as gold wire of grade Zl 99.99 according to specific technical specifications. This designation does not specify a special diameter range.

Product type

The grade confirms the minimum mass fraction of gold, but not the cross-section shape, condition, dimensions, or properties. The typical image of gold material is not a photograph of the measured wire, so supply parameters are taken only from the TU and the batch certificate.

Characteristics

• Type: gold wire
• Grade: Zl 99.99
• Gold: not less than 99.99% by mass
• Document: TU 1866-353-05785324-2002 «Gold wire»

The wire is a long semi-finished product; its purpose depends on diameter, cross-section shape, material condition, and surface quality. Purity Zl 99.99 does not convey these parameters and does not confirm suitability for a specific joining operation. For microwire, tolerances, uniformity along the length, tensile properties, and winding requirements are especially important.

Applications

• conductive and structural elements after coordination of geometry and condition;
• manufacture of meshes, parts, and blanks according to the process sheet;
• further processing of high-purity gold with control of mass and production losses;

What to specify when ordering

Specify round or other cross-section, diameter or profile dimensions, tolerances, soft or hard condition, mass, and length. Coordinate the surface, minimum segment length, spool or coil, packaging, and quality document. If soldering, welding, or forming is required, request mechanical properties and conduct a trial on your equipment.

Safety and storage

Unwind the wire without sharp bends or surface contamination. Thin ends can injure skin and eyes, so use safety glasses, gloves, and appropriate tools. When soldering or thermocompression bonding, control heated parts and flux products. Collect offcuts and fragments separately; store and account for them according to regulations for precious metal products.
