M.A.R.'s Engineering Company Inc. was founded in 1964 by Manuel and Reine Ambrosio and has remained a family-run precision manufacturer ever since. Over the decades, the company expanded its capabilities through new equipment, a second operations department, multi-spindle capacity, and newer CNC technology to better serve customers with complex part requirements. Under Manny Blaine Ambrosio's leadership, the business continued investing in advanced machining and in-house Wire EDM to improve quality control, micro-finish, and tolerance performance. Today, M.A.R.'s Engineering provides complete manufacturing support from prototype through production, helping customers simplify sourcing with one accountable partner for machining, finishing, and assembly.
Copper T2 is commonly selected for components that require strong electrical conductivity, good thermal performance, and reliable machinability for custom designs. It is often used in electrical contacts, connectors, terminals, spacers, and specialty industrial parts where dimensional accuracy and material consistency are important to fit, function, and long-term performance.
