A leader in the metal finishing industry since 1928, Keystone Corporation provides high quality electrodeposited tin/lead (solder) plating for industrial and electronic applications. Tin/lead plating (also known as solder plating) is a co-deposition of tin and lead that provides unsurpassed solderability in critical electronic applications. Alloying a tin plated deposit with lead eliminates the potential for tin whisker growth. Keystone’s Bright solder plating provides an aesthetically appealing reflective finish without the need for reflow.



Keystone Corporation’s tin/lead plating is available for both Rack and Barrel applications. Keystone offers the following alloy compositions in both Bright and Matte finishes:

  • 60/40 (60% Tin 40% Lead)
  • 90/10 (90% Tin 10% Lead)
  • 95/5 (95% Tin 5% Lead)
  • Other alloy compositions available upon request



  • MIL-P-81728
  • AMS-P-81728
