Infrared radiation element and process of producing the same.
摘要
<p>An infrared radiation element and a process for producing the same. An aluminum allowy material consists essentially of 0.3 to 4.3 weight % of Mn, balance Al, and impurities. The alluminum alloy material is heated for dispersing a precipitate of an Al-Mn intermetallic compound at a density of at a minimum 1 x 10<5>/mm<3> for a size of 0.01 mu m to 3 mu m. The heated aluminum alloy material is anodized to form an alumite layer thereon</p>
