Main components of a Bialetti Moka Express pot. Bialetti completed his design for the aluminium Moka Express in 1933. It may also be referred to as a Moka, Moka pot, a Bialetti, a percolator or a stove-top coffeemaker, and in Italian as la Moka, la macchinetta ("the little machine") or la caffettiera. [3]
Moka pots are used over a flame or electric range. Stainless steel pots, but not aluminium, can be used with induction cooking. A number of physics papers were written between 2001 and 2009 utilizing the ideal gas and Darcy's laws, along with the temperature-dependent vapor pressure of water to explain the moka pot's brewing process.

In 1933, Bialetti founded the brand and focused on manufacturing moka pots. The company was later operated by his son Renato Bialetti. [3] After a period of crisis in the 1970s and 1980s, Bialetti merged with Rondine Italia in 1993 [4] and founded a new company named Bialetti Industrie S.p.A., based in Brescia. [5]
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
In 200 series stainless steels the structure is obtained by adding manganese and nitrogen, with a small amount of nickel content, making 200 series a cost-effective nickel-chromium austenitic type stainless steel. 300 series stainless steels are the larger subgroup. The most common austenitic stainless steel and most common of all stainless ...

SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. [1] The name comes from the chemical makeup which is approximately 17% chromium and 4 ...
