Non-Magnetic & Non-Sparking Profile: Ensures safe and interference-free operation in sensitive environments. Critical for stamping shielding components, specialized robotics instrumentation, and aviation sensors that must operate without magnetic disruption.
Premium & Volatile Material Economics: Subject to significant global market fluctuations and consistently commands a much higher price per pound than carbon steel or aluminum, necessitating highly optimized nesting and scrap-reduction stamping layouts.
High Density & Weight Penalties: Substantially heavier than aluminum and comparable in weight to steel. This restricts its use to localized functional components rather than broader structural applications where lightweighting is a primary aviation engineering objective.
Lower Tensile & Yield Strength: Inherently softer and less rigid than structural steels. It is unsuitable for heavy load-bearing frameworks or components subjected to high mechanical impact without structural compromise.
Rapid Surface Oxidation: Bare copper reacts quickly with atmospheric oxygen to form a tarnish layer. While often functionally harmless, it degrades aesthetic appeal and surface contact resistance, frequently requiring immediate post-stamping plating or passivation.
Tooling Adhesion and Galling Risks: The soft, sticky nature of specific high-purity copper grades can lead to material transfer onto the stamping dies during high-speed, high-volume production, requiring Kravzik’s specialized die coatings and advanced lubrication systems to maintain continuous uptime.

Engineered specifically for peak mechanical hardness and extreme fatigue resistance. Delivers the ultimate restorative spring force required for continuous-cycle electrical contacts. Bending is highly restricted; utilized primarily for flat-stamped components requiring absolute dimensional stability.
High-purity copper is inherently soft and highly ductile, which causes it to frequently adhere to standard steel tooling during high-speed stamping. This galling effect degrades the component’s surface finish, introduces dimensional inaccuracies, and forces excessive press downtime for die cleaning and maintenance.
We engineer our progressive dies using specialized carbide inserts and apply advanced PVD (Physical Vapor Deposition) coatings to critical wear components. Combined with finely calibrated boundary lubrication systems, we eliminate material transfer, ensuring pristine surface finishes and uninterrupted, high-cycle production runs.
High-performance copper alloys used for electrical contacts, such as phosphor bronze and beryllium copper, possess high elasticity. This causes significant springback after forming, making it exceptionally difficult to maintain the strict angular tolerances required for robotic assembly and reliable mating connectors.
Our tooling engineers utilize advanced CAE (Computer-Aided Engineering) forming simulations to predict exact alloy springback behaviors before cutting steel. We design precise over-bending stations and integrated coining operations within the progressive die to permanently set the material, guaranteeing repeatable, tight-tolerance geometries.
Copper alloys are tied to volatile global commodity markets and carry a significantly higher baseline cost than steel or aluminum. In high-volume progressive stamping, inefficient strip layouts and excessive carrier web waste generate costly scrap, which rapidly erodes project profitability.
