Suresh metal Finishers Company provides industry-leading precision lead plating services to MIL-L-13808. Our expertise in providing technical barrel, rack and vibratory lead plating process is currently employed in numerous industries including the defense, railway, aerospace, bearing, fire-protection and battery sectors.Suresh metal Finishers lead plating services are employed for highly corrosive applications due to the outstanding performance of lead in corrosive environments especially when dealing with strong mineral acids such as sulfuric acid. Lead also has outstanding solderability making it ideal for use in critical electrical and electronic applications.
Suresh metal Finishers also specializes in demanding plate-to-gauge lead plating services for bearing applications in the defense, aerospace and railway industries. Our dedicated Quality Control department provides prelate, in-process and post-plate dimensional and RMS inspections of inner and outer bearing surfaces to ensure dimensional and surface finish requirements are met. Heavy build lead plating services have been provided up to 0.020 inches in thickness per side.
Lead Plating Services Lead Properties
| This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. Cadmium coatings are used for corrosion resistance and corrosion prevention The as deposited coating (Type I) is useful for the lowest cost protection in a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component. The prime purpose of the supplementary chromate finishes (Types II and III) on the electroplated cadmium is to increase corrosion resistance.Electrodeposited cadmium coatings shall be classified on the basis of thickness as Class 25, 12, 8, and 5. The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. The basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating. Cadmium shall be deposited directly on the basis metal part without an undercoat of another metal except when the part is either stainless steel or aluminum and its alloys. The plating shall be applied after all basis metal heat treatments and mechanical operations. The thickness of the coating everywhere on the significant surface shall conform to the requirements of the specified class. The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests. The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant. The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods.
