An example of DZR brass is the C352 brass, with about 30% zinc, 61–63% copper, 1.7–2.8% lead, and 0.02–0.15% arsenic. The lead and arsenic significantly suppress the zinc loss. [20] "Red brasses", a family of alloys with high copper proportion and generally less than 15% zinc, are more resistant to zinc loss.
Bronze is a better conductor of heat and electricity than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel-base alloys. Bronzes are typically ductile alloys, considerably less brittle than cast iron.
Deformation in the plastic range is non-linear, and is described by the stress-strain curve. This response produces the observed properties of scratch and indentation hardness, as described and measured in materials science. Some materials exhibit both elasticity and viscosity when undergoing plastic deformation; this is called viscoelasticity.
Consumers spend more than 800 times more for bottled water than plain old tap water. Instead: If you don't like the taste of tap water, buy a filter — it's still cheaper than plastic bottles. Amazon
Second, the alloy is capable of greater work-hardening than is the case with pure copper, so that it performs better when used for cutting or chopping. An increase in work-hardening capability arises with an increasing percentage of arsenic, and the bronze can be work-hardened over a wide range of temperatures without fear of embrittlement. [1]

You know plastic bottles aren't great for the Earth, but you probably didn't know how bad they are. Plastic bottles make up the second most common ocean pollutant , accounting for 12% of all ...
Tumbaga is an alloy composed mostly of gold and copper. It has a significantly lower melting point than gold or copper alone [citation needed]. It is harder than copper, but maintains malleability after being pounded. Tumbaga can be treated with a carboxylic acid, such as oxalic acid, to dissolve copper off the surface. What remains is a shiny ...
