3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 alloy, except for the addition of approximately 1% magnesium. It can be cold worked (but not, unlike some other types of aluminium alloys, heat treated) to produce tempers with a higher strength but a lower ductility.
Nov 06, 2007· However, the percentage of magnesium alloys used in automobiles has been traditionally low, with an average of about 10 pounds in a typical domestic model. The reasons for the limited use of magnesium alloys are associated with the intrinsic properties of this family of alloys: low creep and corrosion resistance.

In accordance with ASTM procedure, the yield strength of magnesium alloys is defined as the stress at which the stress-strain curve deviates 0.2 percent from the modulus line (the so-called 0.2 percent offset point). The compressive yield strength of magnesium alloys is defined as the stress necessary to produce 0.2 per cent permanent set.
Compared to the performance of magnesium, aluminum’s lower driving potential and high current capacity per pound are key aspects for its use in long life saline systems. For years, the low current efficiency of commercially available aluminum hindered its use in hodic protection systems.

Accurate comparisons require looking beyond the cost per pound or cost per cubic inch to fully analyze the advantages and disadvantages of each competing process. For instance, the relatively greater strength of metals generally allows thinner walls and sections and consequently requires fewer cubic inches of material than plastics for a given
Anodes are produced to H-1 or AZ-63 specifiions and have a current efficiency of approximately 55% in seawater with a current capacity of 550 amp/hour per pound. Open circuit potential of this alloy is nominally -1.55 volts with respect to a copper-copper sulfate reference electrode. Chemical Composition (%)
