Alloy Steel
Alloy Steel is a type of steel that contains a combination of iron and other elements such as manganese, chromium, or nickel. This combination enhances the properties of the steel, making it stronger, more durable, and resistant to wear and corrosion. Alloy steel is commonly used in industries such as automotive, aerospace, and construction due to its high strength-to-weight ratio and versatility in various applications.
Aluminum
Aluminum is a lightweight, silvery-white metal made by refining bauxite ore. It is known for its high strength-to-weight ratio, corrosion resistance, and good weldability/machining characteristics when alloyed with elements like magnesium and silicon (e.g. 6061 alloy). Aluminum and its alloys are widely used in automotive, aerospace, construction, and other industries requiring strong yet lightweight materials.
Beryllium Copper
Beryllium copper is a copper-based alloy containing beryllium, typically ranging from 0.5% to 3% by weight. This alloy exhibits exceptional strength, hardness, non-magnetic properties, and high electrical and thermal conductivity, making it suitable for applications requiring durability and precision, such as electrical connectors, springs, non-sparking tools, aerospace components, and precision instruments. Its unique combination of properties allows beryllium copper to maintain mechanical integrity over a wide temperature range, resist wear and fatigue, and offer excellent electrical performance.
Brass
Brass is a metal alloy primarily composed of copper and zinc, known for its bright golden-yellow color, corrosion resistance, and malleability. This versatile material finds extensive use in decorative hardware, musical instruments, plumbing fixtures, and various industrial components due to its attractive appearance, durability, and ease of machining. Brass's unique combination of properties, including low friction and resistance to tarnishing, makes it a popular choice across diverse applications.
Bronze
Bronze is a metal alloy primarily composed of copper and tin. Known for its attractive golden-brown color, corrosion resistance, and low metal-on-metal friction properties, bronze alloys are widely used for sculptures, medals, bells, bearings, bushings, and architectural fixtures where durability and aesthetic appeal are valued. Its ability to be cast into intricate shapes also makes bronze suitable for marine hardware and other applications requiring complex shapes.
Carbon Steel
Carbon steel is an alloy primarily composed of iron and carbon, with carbon content ranging from 0.12% to 2.1% by weight. It is one of the most widely used and versatile metallic materials due to its high strength, durability, relatively low cost, and suitability for various manufacturing processes. Carbon steels find extensive applications in construction, machinery, automotive components, tools, and countless other industrial and consumer products where their mechanical properties like hardness, tensile strength, and wear resistance are valued.
Cast Iron
Dura-Bar® Cast Iron is a specialized cast iron alloy consisting primarily of iron with added carbon and silicon. It offers excellent wear resistance, toughness, and the ability to withstand heavy impact and abrasion, making it well-suited for components like crusher jaws, mill liners, and slurry pump impellers used in harsh mining and mineral processing environments. The unique composition allows this cast iron product to provide superior durability for demanding industrial applications requiring high strength and resilience.
Copper
Copper is a reddish-brown, malleable, and ductile metallic element renowned for its excellent thermal and electrical conductivity, corrosion resistance, and ease of fabrication. It finds widespread applications in electrical wiring, plumbing, electronics, industrial machinery components, and the production of alloys like brass and bronze, capitalizing on its unique combination of properties. Despite its strengths, copper is susceptible to oxidation and can be costlier than alternatives like aluminum for certain applications.
Maraging Steel
We carry Maraging Steel in 250 Round Bar, 300 Round Bar, and 350 Round Bar.
Nickel
Nickel is a silvery-white, hard yet malleable and ductile metal. It is highly valued for its corrosion resistance, strength at high temperatures, and ability to produce alloys like stainless steel and nickel-copper alloys with desirable properties like heat resistance and strength. These alloys find widespread applications in industries such as aerospace, automotive, chemical processing, and electronics.
Nickel Silver
Despite its name, nickel silver does not contain silver. It refers to a group of alloys that contain nickel, copper, and zinc and are silvery in appearance. Beyond its color, nickel silver properties include electrical resistance and corrosion resistance, which makes it a popular choice for tableware, marine fittings, and plumbing fixtures. You may also find it used in musical instruments because it produces a bright and powerful sound. We carry nickel silver for sale in the forms of Nickel Silver Sheet/Plate and Round Bar/Rod. As a top nickel silver supplier, we offer these products in full sizes and custom-cut lengths, with delivery available. Price and order online today!
Plastic
Plastics are a wide range of synthetic or semi-synthetic organic polymers that can be molded into solid objects. They are valued for their low cost, ease of manufacture, versatility, and resistance to water, enabling their use across countless applications like packaging, construction, transportation, and electronics. However, plastics also face criticism for their negative environmental impact and issues around recyclability.
Stainless Steel
Stainless steel is an alloy steel containing a minimum of 10.5% chromium, which forms a passive layer of chromium oxide that makes it highly resistant to corrosion, staining, and moisture. Its excellent corrosion resistance, strength, and relatively low cost make it ideal for a wide range of applications, including kitchen appliances, medical equipment, automotive trim, and industrial machinery, where hygiene, durability, and low maintenance are required.
Titanium
Titanium is a low-density, high-strength metallic element known for its exceptional strength-to-weight ratio and corrosion resistance. It is an alloy primarily composed of titanium metal with small additions of elements like aluminum and vanadium. Titanium's unique properties make it ideal for applications requiring lightweight yet durable materials, such as aerospace components, sports equipment, medical implants, and industrial machinery.
Tool Steel
Tool steel refers to a family of carbon and alloy steels containing elements like tungsten, molybdenum, chromium, and vanadium that enhance their hardness, wear resistance, and toughness. These steels are well-suited for manufacturing cutting tools, dies, drill bits, and other tooling components that require high hardness and the ability to retain a sharp cutting edge under severe mechanical stresses and elevated temperatures during metalworking operations. Their high alloy content allows tool steels to be heat treated for exceptional hardness and durability, making them ideal for industrial tooling applications.
