ASTM B122 C77000 Copper Chemical Composition, Grades, Chart and Pdf
ASTM B122 is a C77000 standard for seamless copper alloy plates sheeting, strips, and rolled bars. In particular, it deals with alloy C77000, which is nickel silver or branded as nickel silver. Generally, this alloy is a composite of metal materials such as copper, nickel, and zinc, being highly corrosion-resistant, strong, and also perfectly malleable. The ASTM B1222 referred specification notes the chemical composition, mechanical features, dimensions, tolerances, and test methods for these copper alloy goods. The standard is more likely being used by engineers and manufacturers for quality assurance and performance. The standard is especially useful in the applications such as manufacturing electrical components, musical instruments, decorative items, and architectural applications. Detailed data called chemical composition, grades, charts, and PDF documents can be found in the ASTM B122 standard documentation and in the available documents.

The Advantages and Disadvantages of ASTM B122 C77000 Copper Material Properties, C77000 Properties
Exceptional Electrical Conductivity: OFE Copper C77000 demonstrates excellent electrical conductivity, which is a critical parameter for applications in which the electrical capacity needs to be maximized.
Soft Material: It would allows manufacturing processes with no degradation of physical strength as long as it gets adapting to be shaped, bending and shaping.
Impressive Thermal Conductivity: C77000 displays extraordinary thermal conductivity which makes it applicable as a constituent of spacers, radiators, and other heat transfer devices.
Reasonable Corrosion Resistance: Although, less corrosion-resistant compared to some other copper alloys, it still provide reasonably fine protection against that would be expected in environmental gradient.
Susceptibility to Oxidation: OFHC C77000 exhibits higher purity; consequently, it easily interacts with air or moisture and has to be handled and stored with attention paid to it to avoid oxidation.
Advantages:
High Cost: Customers can expect to pay higher prices for oxygen-free copper (oxygen-free copper) than alternative copper alloys such as C77000 due to its purity and the specialized manufacturing process that gives it high cost in production.
Limited Strength: C77000 material is sort of a soft metal with its insufficient pull and mechanical strength giving rise to serious problems with its use.
Not Ideal for High-Stress Environments: Its low strength and the possibility of oxidation degrade it unsuitable for heavy-structural components.
Limited Work Hardening Ability: Copper, with C77000 alloy, presents an unfavorable work hardening due to negligible resulting strength and toughness after plastic deformation.
Susceptibility to Stress Corrosion Cracking: In spite of wrought low-copper C77000 material being a dominant factor in general corrosion resistance, it isn’t a match in SCC type of environment.
Disadvantages:
