Period 5 element other metal is not easily oxidized in air and is used to coat other metals to prevent corrosion. The firstalloy, used in large scale since 3000 BC, was bronze, an alloy of tin and copper. After 600 BC pure metallic tin was produced. Pewter, which is an alloy of 85–90% tin with the remainder commonly consisting of copper, antimony and lead, was used for tableware from the Bronze Age until the 20th century. In modern times tin is used in many alloys, most notably tin/lead soft solders, typically containing 60% or more of tin. Another large application for tin is
Power Processing Element Power Processing Element The Power Processing Unit (PPU) is a 64-bit dual threaded in-order Power Architecture microprocessor core designed by IBM for use primarily in the game consoles PlayStation 3 and Xbox 360, but has also found applications in high performance computing in supercomputers such as the record setting IBM Roadrunner. In most instances the PPU is joined by a 512 KB L2 cache to form what is called the Power Processing Element (PPE). The PPU is used as a main CPU core in three different processor designs: The PPU is an In-Order processor, but it has some unique traits
