Feasibility assessment of copper-base waste package container materials in a tuff repository

This research developed Science, Environment, Technology, Society (SETS) e-module integrated with predict, observe, explain (POE) model on the subject matter of Earth Layer and Its Dynamics for grade VII students. This study aimed to reveal i) the feasibility of the developed e-module for grade VII students, and ii) the practicality of the developed e-module and its dynamics. This is a developmental research adopting the ADDIE model consisting of five stages, i.e.: analysis, design, development, implementation, and evaluation. The subject of the limited test consisted of 15 students of grade VIII.G of Public Junior High School 8 Yogyakarta. The data were collected using a product feasibility assessment sheet for material and media experts, a product practicality assessment sheet for teachers, and a product readability assessment sheet for students. The results show that the developed e-module was feasible to be used according to the material and media experts and the developed e-module is practical according to teachers and students.

Copper Base Alloy

Abstract CDA C18700 is a copper-base alloy containing lead (nominally 1.0%). The lead is added to impart free-cutting properties to the metal. Although the lead lowers the electrical conductivity of CDA C18700 slightly below that of tough-pitch copper, it still has high electrical conductivity well within the limits needed for most current-carrying requirements. Typical uses comprise electrical motor and switch parts, electrical connectors and screw-machine parts requiring high conductivity. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-533. Producer or source: Copper and copper alloy mills.

Abstract ANACONDA Alloy 360 is a leaded brass and is the alloy most often used for high-speed machining operations; it fills most of the needs for such purposes. Alloy 360 is the standard free-cutting brass and its machinability has become the standard by which all other copper-base alloys are rated. It has medium strength and ductility. Alloy 360 is used for hardware such as gears and pinions where excellent machinability is of prime importance and for all types of automatic high-speed screw-machine products. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-447. Producer or source: Anaconda American Brass Company.

Abstract FEDERAL BRONZE 822 is a copper-base, high-lead bearing bronze with superior resistance to scoring and seizure beyond the endurance and danger limits of ordinary bearing bronzes. It is used in applications involving high speeds, poor lubrication, heat-generating loads, elevated temperatures, dusty and gritty surroundings, or where a liquid other than oil is used as the lubricant. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on casting, heat treating, machining, joining, and surface treatment. Filing Code: Cu-324. Producer or source: Federal Bronze Products Inc..
