Metallizing is the technique of coating metal onto the surface of worn or mismachined parts. Metallized coatings can be protective, functional and/or cosmetic - in most cases all of the above.
At Progressive we use metallization in our repair and reconditioning process. Instead of the costly (and slow) process of replacing an entire hydraulic ram, piston or gland-ring - we can machine away the problematic material, build it up with metallizing wire and machine the product back down to its original specification. This reconditioning process ensures unparalleled cost-savings and turnaround for our customers.
We are able to disassemble, sandblast, metallize, grind and machine entirely in-house. This reduces shipping and handling - keeping the quality high, the cost low and our customers happy.
Used Hydraulic Rams or Pistons, repaired and metallized with Stainless 420, yield customers a cost savings of 60% or more (compared to a new Cast-Iron Ram).
Types of Metallizing Wire we use:
420 Stainless (Rockwell Hardness C-33): A high chrome stainless steel. Excellent corrosion-resistance and wearing qualities. Examples of use: Hydraulic Rams and Hydraulic Pistons, Bearing Journal Surfaces, Armature Shafts, Spun Bearings and Mismachined Parts.
660 Bronze (Rockwell Hardness B-82): An aluminum bronze that is very wear-resistant and has TWO times the strength and hardness of other bronzes. Examples of use: Gland Rings and I.D. of guide areas of pots and hydraulic cylinders.
Aluminum (Rockwell Hardness H-80): An excellent corrosion resistant aluminum alloy for machine element work. Used for building up worn aluminum parts.
