Copper Plating of Bullets and Projectiles \u2013 Copper Chemistries<\/h2>\n

 <\/p>\n

A\"\"<\/a>dvanced Plating Technologies offers a wide range of high-speed copper plating chemistries that are tailored to the specific function or application of the projectile.\u00a0 The deposit hardness can be adjusted based upon the specific application from 100HV100<\/sub> to 250HV100<\/sub>.\u00a0 In copper plating of lead bullets an extremely ductile copper deposit is applied that allows for post-plate swedging to final net shape.\u00a0 Percent elongation of over 25% is attainable with our copper plating of lead bullets or projectiles.<\/p>\n

For frangible applications where a more brittle copper deposit is preferred, Advanced Plating Technologies has developed a hardened copper deposit ensuring the best possible disintegration of the copper deposit at terminal impact.\u00a0 APT has successfully plated \u201cgreen\u201d powdered metal and sintered frangible cores of various configurations for both training and tactical applications within the ammunition industry.\u00a0 Resin impregnation can be provided prior to plating of frangible cores if required by the specific application.<\/p>\n

\"9mm<\/a>Heavy build copper plating of bullets or projectiles for armor-piercing applications are also available.\u00a0 Plating on hardened steel, aluminum or tungsten alloys provides a fully concentric heavy build copper plated jacket with greater jacket uniformity than can be achieved by traditional drawing methods.\u00a0 Due to the strong metallurgical bond between the heavy build copper plating and the bullet core, plated bullets have the distinct advantage of a fused design that greatly aids in terminal performance and overall projectile weight retention.<\/p>\n

Copper Plating of Bullets and Projectiles: Plate-to-Gauge verses Plate-to-Weight<\/h2>\n

 <\/p>\n

\"GB3_1831\"<\/p>\n

Advanced Plating Technologies offers heavy build copper plating on both lead core and frangible core bullets.\u00a0 Due to the ductility of lead substrates, deformation of the lead core during the plating process generally requires plate-to-weight inspection of the rounds.\u00a0 Plating process variation of less than one half of a grain per round is common.<\/p>\n

\u00a0For heavy build copper plating of rigid substrates such as frangible cores or tungsten cores, Advanced Plating Technologies offers plate-to-gauge inspection.\u00a0 In plate-to-gauge applications the plating time\/rate is based upon preplate dimensions of the round to achieve a final targeted dimension.\u00a0 All plate-to-gauge rounds go through a preplate receiving inspection for dimensional verification prior to production release.\u00a0 Multiple in situ measurements of a statistically relevant sample set are made during the plating process to ensure each lot of parts meets the final plate-to dimensions.\u00a0 Plating process variation of less than 0.00025 inches per side is common.<\/p>\n

Copper Plating of Bullets and Projectiles \u2013 Copper Aesthetics<\/h2>\n

 <\/p>\n

\"\"<\/a>Advanced Plating Technologies employs proprietary high-speed copper chemistries that completely eliminate the potential for brown spotting of the copper deposit due to their unique formulation.\u00a0 This plating technology ensures that even extremely porous substrates such as powdered metal frangible cores will be free of brown spotting or workout staining during inventory and shelf storage.<\/p>\n

\u00a0To further protect the appearance of heavy build copper plating of bullets or projectiles, a post-plate inhibit can be applied to the deposit.\u00a0 A 24-hour high humidity test can be passed with APT\u2019s copper inhibit, ensuring that the copper maintains its bright as-plated appearance during storage to final point-of-purchase.\u00a0 The applied inhibit is an invisible organic monatomic barrier that does not affect the size or function of the copper plating on the bullets or projectile.<\/p>\n
