A comprehensive guide to stainless steel investment casting across all five alloy families: austenitic (SS304/316L), duplex (2205/2507), precipitation hardening (17-4 PH), martensitic (SS410/420), and ferritic grades. Covers precision capabilities, heat treatment requirements, ASTM and EN standards, and industrial applications.

Engineers specifying copper bus bars and bus bar connectors have five manufacturing routes to choose from. This guide compares extrusion, machining from billet, CNC bending, sand casting, and investment casting — with a decision matrix and guidance on when converting existing sand castings or permanent mould castings to investment casting delivers measurable improvements in conductivity, surface finish, and material efficiency.

Investment cast copper alloys — ETP, OFHC, CuCr, and CuCrZr — are the engineering standard for switchgear contacts, bus bar connectors, and terminal lugs. This guide covers alloy selection, arc erosion resistance, MV vs. HV requirements, and the quality documentation switchgear manufacturers need from a casting supplier.

Not all copper alloy investment castings are equal — and neither are the foundries that produce them. This guide covers alloy selection across high copper, brass, bronze, and cupronickel families, process control requirements, applicable ASTM standards, and industry applications. Use it to specify correctly, ask better questions, and identify a foundry with genuine metallurgical expertise.

This article explores the unique characteristics of SS 446, the challenges involved in Investment casting it, and why Pahwa MetalTech is the trusted partner for sourcing precision components in this advanced alloy.

In the evolving landscape of marine and aerial propulsion, toroidal propellers have emerged as a groundbreaking innovation. The integration of 3D printing technology into investment casting has transformed the production landscape. By using PLA (polylactic acid) to print patterns, manufacturers can bypass the need for expensive tooling and molds, and open up an opportunity to manufacture parts that were previously possible only by 3D Metal Printing.

Precision Vacuum Casting of Oxygen-Free Copper (OFHC) with <10 ppm oxygen for high-performance electrical & switchgear components

Investment casting of high conductivity copper & brass parts ensures superior performance in high-voltage switchgear. Precision & efficiency

Stainless steel casting alloys like CF3, CF3M, CF8, CF8M, SS304, SS316, and 17-4PH are integral to numerous industries due to their high strength, corrosion resistance, and versatility. These alloys are composed mainly of iron and chromium, along with additional elements like nickel and molybdenum, which contribute to their enhanced properties. The chromium content forms a protective oxide layer on the surface, providing resistance against oxidation and staining. Here are som

Vacuum Investment Casting is an excellent process to manufacture high integrity precision parts very quickly without investment in expensive
