Is alloys resist to corrosion?
Alloys can add corrosion resistance to a metal
Types of alloys?
brass, steel and bronze are the most common alloys. they are made of: brass: 35% zinc and 65% copper - uses, musical instruments steel: 99% iron and 1% carbon - uses, tools, car bodies etc bronze: 87.5% copper and 12.5% tin - uses, boat hardware and screws etc some not so common alloys are alnico (aluminium and nickel and cobalt - used to make magnets) and stainless steel (18% chromium, 80.6% iron, 1% nickel and 0.4% carbon - used to make surgical tools and tableware and cookware.)
Explain why are alloys a useful improvement over pure metals?
Alloys are useful improvement over pure metals because they tend to be stronger.
What are bearing alloys?
properties of bearing alloy
What are three advantages of some alloys when compared to pure metals?
Alloys are sometimes more useful than pure metals because alloys are stronger - or tougher (toughness is resistance to fracture). Pure metals tend to be softer than alloys and therefore tend to get dented, scratched, or broken/fractured more easily. Alloys are often lower cost than pure metals but not necessarily so. As an example, stainless steel is more expensive than pure iron.
Do alloys help to eliminate undesired elements in a metal?
Alloys can help to eliminate undesired elements in a base metal
Why alloys are mixtures but not compounds?
Elements in alloys are bonded by metallic bonding.
Metals include elements and alloys?
Alloys contain metals but also nonmetals.
What metals are elements?
All pure metals are chemical elements; alloys are not elements.
How alloys and compounds are formed?
alloys r homagenous mixture of two or more elements
What does periodic table do to elements?
It organizes them by seperating the elements by metals, alloys, and nonmetals
Alloys have the characteristic properties of which class of elements?
metals
Why are alloys poor conductors of electricity?
Alloys are a combination of two or more elements. Not all alloys are poor conductors, in fact many are used specifically as conductors.
Do alloys rust faster than pure elements?
Only IRON Rusts. Alloys that contain iron may rust. Other alloys do not RUST. They may oxidise. Stainless Steel which is an alloy of iron,.nickel and chrome does not rust. , hence its name Stainless Steel.
Are paper clips compounds?
Paper clips are made from alloys or plastic (a polymer - a compound).
Explain why other elements are often mixed with metals to make alloys?
Alloys have improved features compared with single metals.
Is an element a characteristic of metal?
All metals except alloys of metals are elements, but not all elements are metals.
