Alloy Steel

Alloy steels are a group of quenched and tempered structural steels with an attractive combination of advantages and characteristics. The most important of these are high yield strength (about 3 times that of carbon steel), welding ability, and good toughness at low temperatures. This group of metals enables our customers to choose a product that optimizes strength, toughness, corrosion resistance, and economic return.

Aluminum Bronze

Aluminum bronzes have high strengths (comparable to medium-carbon steel), substantial hardness in the as-cast state, excellent corrosion resistance properties, and are available in a variety of grades and forms. They possess good anti-frictional characteristics, and resist scaling and oxidation at elevated temperatures. Aluminum bronzes can be readily hot worked, possess good cold forming properties, and respond to a form of precipitation hardening.

Beryllium Free Copper

Beryllium free copper is an age hardened copper. It offers good corrosion resistance, moderate mechanical properties, excellent anti-friction attributes, and superior thermal conductivity. Additional characteristics include the retention of hardness at elevated temperatures and reduced cooling cycles.

Copper Nickel

The main wrought copper-nickel alloys chosen for saltwater-bound merchandise contains either 10 or 30 percent nickel. They also have important additions of iron and manganese that are necessary to maintain good corrosion resistance. Some common applications for copper nickel are valves, pump components, fittings, flanges, and other marine hardware components.

Copper-Based Bearing Alloys

Copper-based bearing alloys have several important attributes, including:

A low coefficient of static and kinetic friction versus hard shaft materials
The ability to adapt and adjust to shaft roughness and misalignment
The ability to absorb and discard small contaminant particles
Low shear strength at the bearing-to-shaft interface
Structural uniformity
High fatigue strength
Corrosion resistance
Good scoring resistance
High compressive strength
Typical uses of copper based bearing alloys include bearing bushings, valve stems, marine hardware and light duty gears.

Copper Busbar

Copper has many advantages as a contact material. Most fixed and bolted contacts are in fact copper or copper alloys. Common examples include plug and socket connectors.

Naval Brass(Tin Brasses)

Diversified Metals maintains one of the most comprehensive Naval Brass stocking programs in the country, and it includes Round Bar and Hexagon Bar sizes. Naval brass alloys offer an excellent hot forging ability and good corrosion resistance. These alloys serve many varied fastener, marine hardware, pump & valve, and water flow system industries.

Nickel Alloys

Nickel alloys are defined as those in which nickel comprises a greater proportion of the alloy than any other element. Nickel is most commonly combined with iron, chromium, copper, or molybdenum, and a variety of alloy classes are available. Two separate nickel alloy categories can be distinguished. The first depends primarily on the inherent corrosion characteristics of nickel. The second is based on chromium being the passive element in the mixture (similar to the stainless steels). Nickel alloys offer outstanding and versatile corrosion resistance, making them ideal for marine environments, high temperature, and high stress applications.

Silicon Bronze

Silicon bronze alloys are very strong (similar to mild steel) and have good toughness. Additionally, they exhibit excellent resistance to corrosion by brine and sulfite solutions, non-oxidizing inorganic acids, alkalis, and other mixtures.
