What is Kanthal A1?
Kanthal A1 is a ferritic ironchromiumaluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). The alloy is characterized by high resistivity and very good oxidation resistance. Typical applications for Kanthal A1 are electrical heating elements in industrial furnaces.
What is the composition of the alloy kanthal?
Kanthal is the trademark for a family of iron-chromium-aluminium (FeCrAl) alloys used in a wide range of resistance and high-temperature applications. Kanthal FeCrAl alloys consist of mainly iron, chromium (20–30%) and aluminium (4–7.5 %).
What is the difference between kanthal and Nichrome?
Nichrome (specifically Nichrome 80) is made from nickel and chromium blends. Kanthal is an iron-chromium-aluminum (FeCrAl) alloy. The important difference to note here is that the Nichrome wire contains no Iron. Some people say they can taste a difference.
Which is better kanthal or Nichrome?
Kanthal has a slightly higher maximum operating temperature as well as a higher melting temperature than Nichrome, giving it a slightly longer lifespan than Nichrome. Some people claim that Kanthal wire puts off a slightly metallic taste due to the Iron composition, whereas others claim it does not.
Is kanthal nickel or titanium?
Kanthal wire is a ferritic iron-chromium-aluminum alloy with good resistance to oxidation.
Is NiChrome better than kanthal?
Nichrome behaves very much like Kanthal, but has lower resistance and heats faster. It is easy to coil and holds its shape well when wicking. Nichrome has a lower melting temperature than Kanthal, so you need to be careful when dry burning your coils—they will burn open if you aren’t careful.
What gauge kanthal should I use?
To sum it up, choosing the best type of kanthal wire is AWG 32 gauge, although it ultimately depends on the type of coils you are trying to wrap. Some coil designs will require a thicker gauge, while others will require something a bit thinner.
What are the applications of Kanthal A-1 alloy?
