Pfennig coins minted in 1873-1876 caused such a shock on the previously tranquil market that price more than tripled, leading to a significant expansion of supply.[43]By 1902 the alloy was used in the UK for bullet jackets.[44]By the 1920s, a 70–30 copper–nickel grade was developed for naval condensers. Soon afterwards, a 2% manganese and 2% iron alloy now known as alloy C71640 was introduced for a UK power station which needed better erosion resistance because the levels of entrained sand in the seawater. A 90–10 alloy first became available in the 1950s, initially for seawater piping, and is now the more widely used alloy for this purpose.[citation needed]Brass (copper alloyed with zinc)Bronze (copper alloyed with tin)Copper alloys in aquacultureFreeze branding^ Sakiewicz P.,Nowosielski R., Babilas R.
