ADC12 Aluminum Alloy Die-Casting Solutions

ADC12 is widely used for die-cast components that need good castability, dimensional consistency, and cost-efficient production. It is commonly selected for automotive, EV, electronics, industrial, and general engineering parts such as housings, covers, brackets, and structural support components. Its flow characteristics make it well suited to complex geometries and high-volume manufacturing.

ADC12 is popular because it offers an effective balance of fluidity, pressure tightness, machinability, and production efficiency. It fills complex die cavities well, supports repeatable output in high-pressure die casting, and is commonly used for parts requiring stable dimensions and good surface quality. For many OEM programs, it also helps control overall manufacturing cost.

ADC12 components are typically produced using cold chamber high-pressure die casting. In this process, molten aluminum is transferred from a separate furnace into the shot chamber, then injected into the die under high pressure. Marcus operates cold chamber machines from 60T to 2500T, allowing support for both smaller precision parts and larger industrial components.

Yes. Marcus provides in-house CNC machining after casting, using more than 20 machining centres including 3, 4, and 5 axis equipment. This allows critical features such as bores, threads, sealing faces, and mating surfaces to be finished to tight tolerances. Keeping machining in-house also improves coordination, quality control, and lead-time management.

Marcus offers a broad range of in-house finishing options for ADC12 parts, including anodising, powder coating, wet painting, plating, blasting, vibro polishing, chromation, and heat treatment. Parts undergo pre-treatment such as degreasing, acid cleaning, and conversion coating before finishing. Testing can include ASTM B117 salt spray, XRF coating thickness, and adhesion checks with batch certificates.

Quality control is supported through IATF 16949:2016 and ISO 9001 certified processes, along with structured methods such as DFM, APQP, PPAP, and FAIR where required. Marcus also uses inline inspection, advanced metrology including CMM, and in-house trial validation through T0 and T1 runs. This helps maintain repeatability from tooling approval through serial production.

Yes. Marcus supports new product development with DFM collaboration, simulation-led defect analysis, material guidance, rapid prototyping, and in-house tooling trials. The process is designed to reduce launch risk before full production begins. Validation can include functional testing, dimensional inspection, and customer-specific documentation to help OEM teams move from concept to approved production parts.

Marcus serves a wide range of sectors including automotive, EV, aerospace, electronics, healthcare, energy, and industrial manufacturing. This cross-industry experience is valuable for customers needing complex castings with machining, finishing, or assembly support. It also means the team is familiar with structured quality expectations, production planning, and documentation requirements common in regulated and performance-driven industries.
