Get an Instant QuoteMC66 steel is a high-performance stainless steel known for its excellent hardness, wear resistance, and corrosion protection. It is widely used in CNC machining parts, knives, and industrial components due to its strength and durability. MC66 stainless steel combines toughness with machinability, making it ideal for demanding applications.
ADC12 aluminum and A380 aluminum are both popular die casting alloys with similar properties. The main difference lies in composition: ADC12 is preferred in Asian markets, while A380 dominates North America. Each offers unique casting performance, cost advantages, and machining suitability.
440C stainless steel is a high-carbon martensitic stainless steel known for its excellent hardness, wear resistance, and moderate corrosion resistance. It is widely used in knives, surgical instruments, and precision CNC machined parts. Combining strength and durability, 440C stainless steel offers a cost-effective solution for demanding applications.
420 stainless steel is a hardenable martensitic steel known for high wear resistance, while 316 stainless steel is an austenitic grade with excellent corrosion resistance. Choose 420 for cutting tools and wear parts; select 316 for marine, chemical, or medical applications.
True white anodizing isn’t feasible because anodic pores don’t accept white dye and the oxide’s light-scattering makes whites look gray or chalky. Instead, use powder coating, electrophoretic coating, or PEO/ceramic finishes for durable white on aluminum parts, then specify sealing and gloss to match appearance and corrosion targets.
Micro-arc oxidation (MAO) or plasma electrolytic oxidation (PEO) creates thicker, harder, and more wear-resistant ceramic coatings compared to anodizing. While anodizing is ideal for cost-effective corrosion protection, MAO offers superior durability, thermal resistance, and adhesion, making it more suitable for high-performance CNC machined parts.
420 SS is a grade of Stainless Steel that has good hardness, wear resistance and moderate corrosion resistance. It can be heat treated which means you can harden and temper it to get the exact strength and properties you need. It’s a customizable choice for many applications.
Yes, cast iron is magnetic due to its high iron content and ferromagnetic atomic structure. However, its magnetism varies with type—gray, white, ductile, or alloyed cast iron—and environmental factors like temperature or impurities. Cast iron can attract magnets, but its strength depends on composition and processing.
