Many have similar tin contents to contemporary bronze artefacts and it is possible that some copper-zinc alloys were accidental and perhaps not even distinguished from copper.

Many common bronze alloys have the unusual and very desirable property of expanding slightly just before they set, thus filling in the finest details of a mold.

Many alloys contain zinc, including brass, an alloy of copper and zinc.

Many of the associated tellurides can be treated as metallic alloys.

Many structural alloys corrode merely from exposure to moisture in the air, but the process can be strongly affected by exposure to certain substances.

Many amorphous alloys are formed by exploiting a phenomenon called the " confusion " effect.

Many miniature manufacturers, anticipating that other states would also impose bans, began making figures with lead-free alloys, often at increased price.

Many precious metals are used in the form of alloys.

Many alloys also contain titanium as a minor additive, but since alloys are usually categorized according to which element forms the majority of the material, these are not usually considered to be " titanium alloys " as such.

Many alloys that do not undergo martensitic transformation have been subjected to the same treatments as steels — that is, cooled with no provisions for cold work.

Many acid rock discharges also contain elevated levels of potentially toxic metals, especially nickel and copper with lower levels of a range of trace and semi-metal ions such as lead, arsenic, aluminium, and manganese.

Many sources still describe the subsequent unpainted aluminium finish as " silver ".

Many steel components were replaced by aluminium counterparts.

Many systems use an aluminium oxide or zirconium oxide or zirconia core instead of metal that makes complete porcelain restorations.

Many other elements, both common and exotic, ( including not only metals, but also metalloids and nonmetals ) can be present ; chromium, cobalt, molybdenum, tungsten, tantalum, aluminium, titanium, zirconium, niobium, rhenium, carbon, boron or hafnium are just a few examples.

Many minerals are also essential in small quantities including iron, calcium, magnesium and sulphur ; and in very small quantities copper, zinc and selenium.

Many enterprises within the copper, coal, iron, nitrate, and steel industries were expropriated, nationalized, or subjected to state intervention.

Many different types of copper IUDs are currently manufactured worldwide, but availability varies widely by country.

Many conventional coaxial cables use braided copper wire forming the shield.

Many Cornish and Finnish immigrants arrived in the Houghton area to work in the copper mines ; both groups have had a great influence on the culture and cuisine of the local area.

Many hollow-point bullets, especially those intended for use at high velocity in centerfire rifles, are jacketed, i. e. a portion of the lead-cored bullet is wrapped in a thin layer of harder metal, such as copper or mild steel.

Many other metallic ores and minerals oxidize and hydrate to produce colored deposits, such as chalcopyrites or CuFeS < sub > 2 </ sub > oxidizing to copper hydroxide and iron oxides.

Many of the rarer minerals were found in mines, and he mentions the famous copper mines of Cyprus and the even more famous silver mines, presumably of Laurium near Athens, and upon which the wealth of the city was based, as well as referring to gold mines.

Many companies processed the massive piles of " overburden " that had been removed from copper mines, or expanded the existing open-pit mines to extract the gold ore. Gold mines as widespread as the Robinson project near Ruth, and AmSelco's Alligator Ridge mine from Ely, kept the town alive during the 1980s and 1990s, until the recent revival of copper mining.

Many other oxyanions form complexes ; these include copper ( II ) acetate, copper ( II ) nitrate, and copper ( II ) carbonate.

Many thousands of tons of copper were unearthed over the years until deposits were exhausted.

Many blacksmiths also incorporate materials such as bronze, copper, or brass in artistic products.

Many swords contain an alloy of copper, tin and other elements including nickel, magnesium, and cobalt.

Many superconducting ceramic materials ( the high temperature superconductors ) have perovskite-like structures, often with 3 or more metals including copper, and some oxygen positions left vacant.

Many of these insulators survived the 1906 earthquake and fires, despite temperatures high enough to soften the iron poles and melt the copper cables.

Many forms of illegal activities take place such as smuggling of weapons, narcotics, lumber, copper, gemstones, marble, vehicles, electronic products, as well as ordinary consumer goods.
