Product Overview
INVEST-LITE-05 is a high-precision aluminum investment casting engineered for demanding industrial applications where weight, dimensional accuracy, and structural integrity are critical. Manufactured using the lost-wax process from aerospace-grade A380 aluminum alloy, this compact casting delivers exceptional surface finish and tight geometric tolerances—certified to ISO 8062-CT4, the highest standard for dimensional accuracy in investment castings. With a net weight of just 0.8 kg and compact footprint (120 × 85 × 45 mm), it exemplifies lightweight design without compromising strength or thermal stability. Fully T6 heat treated, the part achieves optimal mechanical properties: high tensile strength, excellent machinability, and superior corrosion resistance—making it ideal for high-mix, low-volume custom production runs in precision manufacturing.
This component belongs to our INVEST-LITE series—specifically developed for customers requiring certified investment castings with rapid turnaround, minimal post-processing, and full RoHS compliance. As a turnkey solution from a specialized custom forging and machining partner, INVEST-LITE-05 supports agile prototyping and small-batch production across global supply chains.
