Discover how PIM Alloy Materials offer superior corrosion and oxidation resistance, environmental durability, and mechanical performance for advanced applications. Metal injection molding is a high-tech technology derived from plastic injection molding.
MIM of plastic injection molding, high polymer chemistry powder metallurgy and metal materials, and other disciplines. Powder metallurgy can take advantage of the billet mold injection molding parts, by degreasing, sintering, and rapid production of high-density, high-precision, complex shape metal structural parts, to quickly and accurately ideas materialized into a certain structure and functional properties of metal products in order to achieve high-volume, large-scale production.
Powder metallurgy thanks to a large amount of binder as a means to enhance flow, like injection molding can process arbitrarily complex metal parts, this is impossible to achieve by traditional molding of powder metallurgy; Powder metallurgy is a kind of net-shape forming technology, with almost no subsequent processing, parts manufacturing cost is greatly reduced, so need dozens of machining process that can obtain a forming production parts.
In addition, the uniformity of flow during injection molding filling cavity and making the metal injection molding products everywhere density is very homogeneous, eliminating the inevitable in the powder metallurgy mold process of density inhomogeneity. And as a result of micro-powder, the product can reach very high density after sintering, thus, the mechanical properties of MIM products are generally superior to the molding process and precision casting and processing of the resulting product and was internationally hailed as “one of the most popular parts forming technology”
Understanding PIM Alloy Materials and Their Environmental Performance
PIM Alloy Materials combine innovation, precision, and environmental adaptability. Their advanced processing techniques enable the creation of parts that meet stringent industrial and environmental standards. The environmental properties of PIM alloys are essential in determining how these materials respond to various chemical, thermal, and mechanical exposures.
When evaluated for sustainability, PIM Alloy Materials often outperform conventionally forged metals due to their efficient production process, reduced waste, and enhanced recyclability. The injection molding process minimizes raw material loss and energy consumption, making it a greener alternative to traditional metallurgical techniques. Moreover, modern advancements have introduced biodegradable binders and eco-friendly lubricants that further reduce the environmental footprint of PIM manufacturing.

The erosion environment is complex and is associated with multiple factors, including the test fluid and some details such as ventilation (gas), PH, concentration of halogen ions, contact with other materials, etc. Accordingly, any discussion of PIM material’s environmental tolerance should include from sintering microstructure, heat treatment, and test conditions to the details such as the quantitative measurement of corrosion resistance. For this, it will highlight the material behavior and success. For many applications, it is best to PIM test specimens to the target use environment to ensure the performance of the material.
PIM alloy has been considered as knee and hip implants in an extreme case, Cobalt – chromium alloy has been used in these applications in the field of testing, but has not yet been put into use. In addition, it has carried on quantitative antibacterial testing, an important finding is added in the PIM304L stainless steel mass fraction of 3% copper can inhibit the growth of bacteria. This is the situation of PIM can according to the application of materials change its chemical composition.
Also, there are other biocompatibility materials testing, including tantalum, titanium, hydroxylapatite, and titanium hydroxyapatite composite material. The latter is used for animal testing. No nickel stainless steel artificial saliva tests show that the nickel release rate can be two orders of magnitude lower than ordinary stainless steel. Therefore, early data is good, but before being put into the PIM implant products also needs more tests.
Corrosion Resistance and Oxidation Properties of PIM Alloy Materials
Stainless steel and titanium is usually used as a corrosion-resistant material, but some areas also use pure nickel. Alumina ceramics under acidic conditions, such as corrosion resistance, but in alkali solution erosion. The corrosion resistance of the PIM material tests shows that its performance is usually fair and forging materials. Impurities can reduce the corrosion resistance of the material, but the sintering can make volatile impurities out, therefore, the PIM materials show that corrosion resistance is usually better than another processing method.
The corrosion resistance of the test the PIM products is mainly directed against the stainless steel. PIM processing of stainless steel with austenitic, ferritic, and martensitic precipitation hardening or different levels, such as the material having at least a mass fraction of 12% chromium. 300 grades of austenitic stainless steel, its good corrosion resistance, excellent toughness and non-magnetic etc, are widely used in consumer products. Most of all stainless steel, the PIM applications are 17-4 pH (AISI630) levels of precipitation hardening stainless steel. The mechanical properties of stainless steel can be sintered after heat treatment in a wide range of adjustments, which makes its application range from magnetic sensors to surgical tools.
PIM Alloy Materials in Testing and Real-World Applications
The corrosion resistance of metal injection molding of stainless steel is accomplished by means of salt spray test, immersed in artificial sweat (artificial time!), artificial spit liquid (artificial saliva), boiling water, copper sulfide (copper sulfate), nitric acid (nitric acid), hydrochloric acid (hydrochloric acid), acid (sulfuric acid), drift chlorine water (chlorine bleach) and ferric chloride, (ferric chloride).In addition, the original electrochemical grinding is used to characterize the passivation collapse and pitting. When corrosive becomes a major focus, PIM of 316L is the most commonly used stainless steel, but if you need a higher intensity, PIM17-4PH can be used.
Tests have shown that the corrosion resistance of PIM stainless steel products is comparable to, and sometimes better than, forged materials. This is particularly important in industries such as automotive, aerospace, and medical devices, where durability and reliability are non-negotiable. The oxidation resistance of PIM Alloy Materials ensures that they maintain their mechanical integrity even under extreme thermal conditions, making them ideal for high-performance machinery and components exposed to heat, pressure, and moisture.
