E-coating, also known as electrophoretic deposition (EPD) or electrocoating, is an electrochemical surface coating process where electrically charged paint particles are deposited onto a conductive workpiece immersed in a water-based ...

Quenching and Tempering is a two-stage heat treatment process that dramatically increases the hardness and strength of steel. The workpiece is first heated above the critical temperature (austenitizing), then rapidly ...

Nitriding is a surface hardening process that diffuses nitrogen into the surface of a steel workpiece at temperatures typically between 450°C – 600°C, below the lower critical temperature (Ac1). Unlike ...

Overview Annealing is a heat treatment process that involves heating a material above its critical temperature and then slowly cooling it at a controlled rate. This process eliminates internal stresses, ...

Carburizing is a surface hardening process that increases the carbon content on the surface of low-carbon steel parts (typically < 0.25% C) while leaving the core relatively soft and tough. ...

Hard anodizing, also known as Type III anodizing or hard coat anodizing, is a specialized electrochemical process that produces an extremely thick and dense aluminum oxide layer. By using lower ...

Color anodizing, also known as dyed anodizing or electrolytic coloring, is a versatile surface treatment process that produces vibrant, durable colors on aluminum through either dye absorption or electrolytic coloring ...

Overview Clear anodizing, also known as Type II anodizing or standard anodizing, is an electrochemical process that converts the aluminum surface into a durable aluminum oxide layer. Unlike paint or ...

Black anodizing is a Type II anodizing process combined with an integrated coloring step that produces a rich, deep black finish on aluminum. The black color is achieved either through ...

Titanium Grade 2 (Grade 2 CP Ti), also known as commercially pure titanium, is an unalloyed titanium grade with a minimum purity of 99.3% titanium. It represents the most widely ...

Titanium Grade 5 (Ti-6Al-4V), often called the "workhorse" titanium alloy, is an alpha-beta titanium alloy containing 6% aluminum and 4% vanadium. It accounts for over 50% of all global titanium ...

AZ91D is the most widely used magnesium die-casting alloy in the world, accounting for approximately 90% of all magnesium castings produced. An aluminum-zinc-magnesium alloy with approximately 9% aluminum and 1% ...

Zamak 3 (also known as ZAMAK 3 or Alloy 3) is the most widely used die-casting zinc alloy in the world. Part of the Zamak family of zinc-aluminum-magnesium-copper alloys, Zamak ...

S136 (also known as AISI 420 modified, DIN 1.2083, or ASSAB 840 Supreme) is a premium corrosion-resistant martensitic stainless mold steel that occupies the top tier of injection mold steel ...

Stainless Steel 303 is a free-machining austenitic stainless steel specifically designed to overcome the machining challenges associated with standard austenitic grades like 304. The addition of selenium and/or sulfur (0.15–0.35%) ...

Stainless Steel 304 is the most widely used austenitic stainless steel grade, accounting for more than 50% of all stainless steel production worldwide. Its exceptional corrosion resistance, excellent formability, and ...

Stainless Steel 316 is the second most widely used austenitic stainless steel and is specifically engineered for environments requiring superior corrosion resistance. The key differentiator from 304 is the addition ...

Stainless Steel 416 is the most easily machinable of all stainless steel grades, making it the default choice when high-volume precision machining is required. As a martensitic (ferromagnetic) stainless, it ...
