Tri-M3 Data

 PDF - Data Sheet

Electro-Specs new TRI-M3^TM finish represents a dramatic improvement in plating RF connectors and components that desire high corrosive resistance and tarnishing behavior. With characteristic and shelf life far surpass traditional silver, TRI-M3^TM plated connectors will also provide better electrical performance than nickel. Silver has excellent electrical properties but tends to tarnish and breaks down over time. Nickel provides a longer shelf life and wears characteristics, but exhibits poor inter modulation performance, high permeability, and poor screening effects. TRI-M3^TM coated connectors and components provide the following characteristics:

• Excellent corrosion resistance (even in harsh environments)
• Low surface friction that is approximately 70% of silver
• High conductivity
• Superior abrasion resistance that is ideal for mating applications
• Solders easily with standard 60/40 Sn-Pb solder
• Low internal stress permitting forming of plating articles
• Ability to plate over existing metals or provides a excellent undercoating
• Excellent deposition qualities and uniformness
• Requires less thickness to provide protection and wear resistance
• Non-magnetic finish
• Can be rack or barrel plated depending upon your need
• Very economical alternative to other types of finishes
