Special Services

At Source 21, we go beyond just supplying high-quality metals—we offer specialized services tailored to your exact specifications. Whether you need high-tempers, tight tolerances, specialty plating, or precision processing, we provide custom solutions to ensure your materials meet the highest performance standards.

Custom Tempers & Specialty Processing

We understand that standard materials don’t always fit specialized applications. That’s why we offer:

High-Tempers & Specialty Tempers

Custom tempering options for increased hardness, durability, and performance

Tight Tolerances

Precision processing with narrow width, gauge accuracy, and exact specifications

Custom Finishes

Surface treatments for enhanced corrosion resistance, conductivity, and aesthetics

Plating Services for Enhanced Performance

To improve the durability, conductivity, and corrosion resistance of our metals, we offer specialty plating options, including:

Tin Plating – Enhanced solderability and corrosion resistance, commonly used in electrical and food-grade applications
Silver Plating – Superior conductivity and oxidation resistance, ideal for electrical contacts and high-heat environments
Zinc Plating – Corrosion-resistant coating for added protection in harsh environments
Nickel Plating – Improved wear resistance, conductivity, and oxidation protection, used in automotive, aerospace, and industrial applications
