HIGH SPEED Steel Alloys – These steels are used to produce hardness values in excess of 70 HRC. The ultra hard high-speed steels will demonstrate high impact values. In other words, they are very tough under repeated impact such as milling cutters.

M-SERIES – These steels are employed when higher forging temperatures are being used, as opposed to temperatures used on alloy carbon steels. This group of steels is used for high temperature forging, hot extrusion or hot metal die casting—such as aluminum die casting and magnesium die casting.

T-SERIES – Tungsten is a very strong carbide former and will produce very high as quenched hardness values. All of the high-speed steels (molybdenum and tungsten) are known as secondary hardening steels. In addition, this group of steels has the ability to cut at red heat without losing its hardness value. The addition of cobalt enables an even higher operating temperature, before losing the as quenched hardness.

Magnesium – Magnesium alloys are very low density (1.7 g/cc) and can be treated to reasonably high strengths. Magnesium alloys are available in both wrought and cast forms. Its low density

Brass – Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 °C, 1652 to 1724 °F, depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses. The density of brass is approximately .303 lb/cubic inch, 8.4 to 8.73 grams per cubic centimetre.

Today almost 90% of all brass alloys are recycled.Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet. Brass scrap is collected and transported to the foundry where it is melted and recast into billets. Billets are heated and extruded into the desired form and size.

Bronze – Typically bronze only oxidizes superficially; once a copper oxide (eventually becoming copper carbonate) layer is formed, the underlying metal is protected from further corrosion. However, if copper chlorides are formed, a corrosion-mode called “bronze disease” will eventually completely destroy it. Copper-based alloys have lower melting points than steel or iron, and are more readily produced from their constituent metals. They are generally about 10 percent heavier than steel, although alloys using aluminum or silicon may be slightly less dense. Bronzes are softer and weaker than steel—bronze springs, for example, are less stiff (and so store less energy) for the same bulk. Bronze resists corrosion (especially seawater corrosion) and metal fatigue more than steel and is a better conductor of heat and electricity than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel-base alloys.

T Series Steel Alloy – The low hardness of copper partly explains its high electrical conductivity (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest among pure metals at room temperature.This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively.As with other metals, if copper is placed against another metal, galvanic corrosion will occur.

PLASTIC Materials– Delrin® AF Blend is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It is a combination of PTFE fibers uniformly dispersed in Delrin® acetal resin. This combination offers better wear characteristics than unfilled Delrin®.
Delrin® AF Blend, supplied as a 2:1 blend of Delrin® AF100 and Delrin® 150 resins, has excellent sliding/friction properties. Bearings made of Delrin® AF Blend can operate at higher speeds while exhibiting reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficient of friction is closer than with most plastics.

Delrin® AF Blend retains 90% of the strength that is inherent in unmodified Delrin acetal. Some properties are changed due to the addition of the softer PTFE fiber. The natural color of Delrin® AF Blend is dark brown.

Acetal Copolymer Acetal Sheets and Acetal Rods (aka POM) acetal copolymer provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, acetal is also characterized by a low coefficient of friction and good wear properties especially in wet environments. Because of its high strength, modulus, and resistance to impact and fatigue, Acetal is used as a weight-saving metal replacement. Acetal copolymer overcomes the common problem of centerline porosity in large shapes of Acetal Homopolymer (aka Delrin)

  • Acetal Copolymer is compared to Delrin (DuPont brand Acetal Homopolymer) where centerline porosity is a concern.
  • Acetal copolymer is produced under several brand names including Celcon, Ultraform & Acetron.
