Blank ‘Golden Splendor’ from alloy ZlSrPdM 375-100-38

‘Golden Splendor’ is the name of a high-readiness jewelry blank. The material of the item is confirmed as ZlSrPdM 375-100-38, and the supply document refers specifically to jewelry blanks.

What this item is

The trade name does not reveal the shape of the product, so unspecified dimensions, inserts, or degree of finishing are not assigned to the blank. These parameters are determined by the version. The alloy grade and TU serve as the basis for an accurate order.

Composition and documents

• Grade: ZlSrPdM 375-100-38
• Gold: 37.5–38.0% by mass
• Silver: 9.5–10.5% by mass
• Palladium: 3.5–4.1% by mass
• Copper: balance
• Supply document: TU 9641-823-05785324-2005

The gold–silver–palladium–copper alloy has a declared gold fineness of 375 and a separate palladium range. The letters and numbers describe the chemical grade, not the product geometry. Copper makes up the remainder to full mass. For production calculations, the actual batch analysis, material condition, and tolerances of the specific semi-finished product are required.

Applications and technological role

• subsequent processing of the jewelry blank according to the working drawing;
• surface finishing, assembly, and polishing after mass and allowance control;
• production of 375-fineness items upon confirmation of composition and assay control requirements;

What to agree before ordering

The supplier is provided with the drawing or version code, mass, dimensions, tolerances, surface requirements, and quantity. You should request the batch certificate, actual component fractions, melt number, completeness, and packaging. If soldering, setting, or deformation is planned, agree on the technological state of the blank and allowances. The name ‘Golden Splendor’ must be supplemented with the grade and TU.

Safety and handling

Protect the surface from contamination by foreign metals. Cutting, grinding, and polishing should be carried out with local exhaust and eye protection; collect dust and trimmings separately. When heating, use solder and flux only according to a proven technology. The safety data sheet and company rules take precedence.
