Users that depend on copper spark plugs use higher quantities of components, and sometimes spend more on replacement parts than businesses that use higher quality iridium spark plugs. This is why cheap spark plugs need changing so regularly: as soon as the copper central electrode starts to deteriorate, engine performance will start falling off rapidly, and you run the risk of a sudden spark plug failure that could stop your engine entirely. While copper is equally good at conducting electricity as iridium – and is thus perfectly acceptable as a spark plug material – copper quickly begins to deteriorate with use. The big difference between iridium spark plugs and normal copper spark plugs is durability. Why is this so, and what are the main differences between iridium and normal spark plugs? Iridium Spark Plug vs Normal Spark Plug For more information, do not hesitate to contact us.However, in terms of practical performance, price, and usability for various applications, there is a huge difference between iridium spark plugs and every other spark plug category, with iridium spark plugs being the best component you can buy. HARDENING oF STAINLESS STEEL USING THE BORINOX® PROCESSĪre you looking for a way to harden stainless steel without destroying the wear protection and corrosion resistance? Then make use of our unique BORINOX® process. It can be alloyed with iron and carbon, for example. As a refractory metal, it is highly resistant to heat and abrasion, which is why titanium and its alloys are popular. Even in its pure form, titanium is harder than many steel forms. While it does not quite compare to other any other metal on this list in terms of Brinell Hardness, titanium has an impressive strength to weight ratio. Since it is easier to handle as well as more abundant than platinum group metals, chromium is a popular element used in alloys. Chromium is valued for its high corrosion resistance as well as its hardness. On the Mohs scale, which measures scratch resistance, it is found among the top. Chromium (687-6500 MPa)Ĭhromium is an element often found in alloys, such as stainless steel. When it is alloyed with other platinum group metals (such as iridium, platinum and palladium) it can be used in many different areas where hardness and durability are needed. This is also why Osmium does not melt until 3033 ☌, a temperature that makes it difficult to work with the metal. In fact, it is the densest, naturally occurring element on Earth with 22.59 g/cm3. Osmium belongs to the platinum group metals and displays a high density. Borocoat for example, optimizes the hardness of steel without making it brittle. There exist many techniques of tempering steel to improve the wear protection of steel, heat tolerance and protection against abrasion. Due to the many variations and levels of quality steel can adopt, there is no uniform hardness value. It is the most used material in construction, mechanical engineering, and other industries. Steel is an alloy metal made of iron and other elements, such as carbon. Iridium ranks among one of the rarest Elements on Earth’s surface, as well as one of the most corrosion-resistant elements. Since it is very hard, iridium is also quite brittle, which is only aggravated by its very high melting point of over 2,000 ☌. Iridium belongs to the platinum group of metals, resembling platinum in its look. Like Tungsten, Iridium is a chemical element that shows signs of high density and a tolerance of high temperatures. Tungsten is often utilized to create hard alloys, such as high speed steel, to increase protection against abrasion as well as improve electrical conductivity. In its rare form, tungsten is hard to work with due to its brittleness, which can be changed when turned pure. Also known as Wolfram, the rare chemical element exhibits a high density (19.25 g/cm3) as well as a high melting point (3422 ☌/ 6192 ☏). Tungsten is one of the hardest metals you will find in nature.
