Inclusion in this list does not constitute or imply any representation or warranty by the LBMA as to creditworthiness or as to the services or goods supplied or quality or compliance with any specification relating thereto.
However, bars produced by these organisations prior to their transfer to this list continue to be acceptable as good delivery.

  NationMaster.com - Encyclopedia: Alloys
The properties of alloys are frequently far different from those of their constituent elements, and such properties as strength and corrosion resistance may be considerably greater for an alloy than for any of the separate metals.
Another alloying technique is ion implantation, which has been adapted from the processes used to produce computer chips; beams of ions of carbon, nitrogen, and other elements are fired into selected metals in a vacuum chamber to produce a strong, thin layer of alloy on the metal surface.
An alloy with two components is called a binary alloy; one with three is a ternary alloy; one with four is a quaternary alloy.

The old steel cable of a colliery winding tower Steel is a metal alloy whose major component is iron, with carbon being the primary alloying material.
In practice, some alloys are used so predominantly with respect to their base metals that the name of the primary constituent is also used as the name of the alloy.
The term "alloy" is sometimes used in everyday speech as a synonym for "aluminium alloy"; one example of such usage is the "alloy wheels" which might be fitted to an automobile.

 Braze Alloys / Silver Solders - Carbide Processors, Inc.
The alloys are sensitive to heating as is the carbide.
Generally the less we heat the alloy and the carbide the better it is. Also, by underheating the braze alloy or solder, we can leave a hump or slug of alloy in the middle of the tip which is where it is needed for maximum brazing effectiveness.
Alloy suppliers use the term Cadmium-free to mean alloys that match descriptions according to industry standards including SAE, AWS and ASTM standards as well as federal standards as referenced in CFR 1910.1200.

 The Hendrix Group - corrosion of copper in oil and gas wells
Copper and copper alloys are widely used in many environments and applications because of their excellent corrosion resistance, which is coupled with other desirable properties, including superior electrical and thermal conductivity, ease of fabricating and joining, and resistance to biofouling.
Copper and its alloys are susceptible to rapid attack in oxidizing acids, oxidizing heavy-metal salts, and sulfur and ammonia and their compounds.
Copper and copper alloys are susceptible to several forms of corrosion in downhole environments including: (1) general corrosion, (2) pitting, (3) dealloying, (4) galvanic corrosion, (5) erosion-corrosion, (6) stress corrosion cracking and, (7) intergranular corrosion.

 eFunda: General Information on Titanium Alloys
Titanium alpha alloys are alloys that typically contain aluminum and tin, though they can also contain molybdenum, zirconium, nitrogen, vanadium, columbium, tantalum, and silicon.
Alpha alloys do not generally respond to heat treatment, but they are weldable and are commonly used for cryogenic applications, airplane parts, and chemical processing equipment.
Alpha-beta alloys can be strengthened by heat treatment and aging, and therefore can undergo manufacturing while the material is still ductile, then undergo heat treatment to strengthen the material, which is a big advantage.

 Titanium Alloys - Classifications
It is common practice in the metallurgical industry to refer to titanium alloys by their structure, hence alpha, alpha-beta, and beta alloys, examples of whichare given in table 1.
While the alpha alloys cannot be heat treated to increase strength, the addition of 2.5% copper to titanium results in a material which responds to solution treatment and ageing in a similar way to aluminium-copper alloys.
Aluminium as an alloying addition to titanium is an alpha stabiliser and is found in many of the commercially available alloys.

The aluminium alloys used do have a low strength and need to be reinforced with a galvanised or aluminium coated high tensile steel wire in each strand.
Their old system used 3 digits, the new Unified Numbering System for Metals and Alloys (UNS) system uses five digits preceded by the letter C. As an example the forging brass known as Copper alloy 377 is known as C37700 under the UNS system.
These alloys are commonly known as “Nickel Silvers” due to the colour of the alloy.
