Wrought strip

Most grids are cast or mechanically expanded from cast or wrought strip. Historically, negative and positive grids have been the same however, with the advent of specialized batteries and extreme performance demands, this is less likely. However if these plates are different, it is generally in configuration, alloy, and/or thickness. 

Wrought lead—calcium—tin alloys contain more tin, have higher mechanical strength, exhibit greater stabiUty, and are more creep resistant than the cast alloys. RoUed lead—calcium—tin alloy strip is used to produce automotive battery grids in a continuous process (13). Table 5 Hsts the mechanical properties of roUed lead—calcium—tin alloys, compared with lead—copper and roUed lead—antimony (6 wt %) alloys. 

Tin is used in various industrial appHcations as cast and wrought forms obtained by rolling, drawing, extmsion, atomizing, and casting tinplate, ie, low carbon steel sheet or strip roUed to 0.15—0.25 mm thick and thinly coated with pure tin tin coatings and tin alloy coatings appHed to fabricated articles (as opposed to sheet or strip) of steel, cast iron, copper, copper-base alloys, and aluminum tin alloys and tin compounds. 

Sheet and Strip. The manufacture of wrought copper materials starts with either semicontinuously cast slabs that are hot roUed, or cast plate that is thin enough, near 13 mm (0.5 in.), to be cold roUed directly. The surfaces of both hot roUed slabs and as-cast plate are milled to remove defects before proceeding to cold rolling and annealing operations. 

Tbngsten (piue W, doped W, W-Re) is commercially available as wrought products (sintered bars, billets, forgings, rods, pins, disks, cylinders, tubes, sheet, strips, ribbons, wires) as well as in the form of a broad variety of shaped parts (crucibles, springs, heating elements, rivets, etc.).

Phosphor hronze is available in a wrought condition as sheet, strip, plate, rod, bar, wire and tube and also as cast materials. 

As a wrought alloy in the form of wire and strip containing 5% tin and up to 0.4% phosphorus with the remainder copper, the alloy can be heat-treated. In the heat-treated condition it has good elastic properties as well as corrosion-resistance and is used for springs, diaphragms, clutch discs, fasteners and lock-washers. 

HSLA steels usually require 25 to 30% more energy than do structural carbon steels. Commercially HSLA steels are available in all standard wrought forms (i.e., sheet, strip, plate, structural shapes, bar-size shapes, and special shapes).
