To subject (glass or metal) to a process of heating and slow cooling in order to toughen & reduce brittleness.
The positive pole of an electrolytic cell. The anode is the electrode where oxidation occurs.
Abbreviation for the American Society of Testing Materials. The organization sets standards for testing, evaluating, and manufacturing of materials.
A nonmagnetic solid solution of ferric carbide or carbon in iron, used in making corrosion-resistant steel.
The electrode opposite the anode. Electrons enter at the cathode end causing a reduction condition where the anode end undergoes a n oxidation condition.
The electrochemical deterioration of a metal caused by atmospheric or induced chemical reactants.
A solution that will conduct an electrical current. Rainwater carrying dissolved salts picked up from the atmosphere is an electrolyte.
The rate of expansion of a material related to the change in temperature.
A condition which develops from repeated or cyclical stresses below the tensile strength of the material. This condition leads to eventual rupture of the material.
Of or containing iron, especially with valence 2 or a valence lower than in a corresponding ferric compound.
An etching compound used to prepare metal surfaces by removing oxides and scale compounds.
Corrosion conditions that are created from two dissimilar metals or between two dissimilar areas on metal. An electrical current develops between the metals ans the more reactive metal decays in relation to the more noble metal.
The coating of metal with zinc.
Metal that is easily formed or shaped.
The visible distortion of a flat metal surface.
The surface oxide, carbonate, sulfate, or chloride that develops on the surface of metal.
The hardness and strength produced by mechanically working and thermal treatment.
The ratio of maximum load to unit cross section. Also know as ultimate strength. The resistance of a material to a force tending to tear it apart, measured as the maximum tension the material can withstand without tearing.
A lead-tin alloy coating.
A zinc-tin alloy coating.
A term to describe the copper alloy Nickel Silver. Also called German Silver or Dairy Bronze.
As commonly applied to copper and copper-base alloys, yield strength is the stress which will produce a .5 percent extension under load. It is known as "Yield Strength" (.5 percent extension) The stress a material can withstand without permanent deformation.
Attached is a photo of the flashing at 199 E. Lake Shore Drive. We wanted to let you know that you did a really nice job on the fabricating.
