Model: YM-A Aluminum Comparator Block

Through the physical and chemical test type A block material for LY12 aluminum alloy for materials, the chemical components conform to the provisions of ASTM,GB/T3190

By means of a micrometer measurement block length is 76 + 0.1 ㎜, and the width fifty + / - 0.1 ㎜, thick and ± 1 ㎜. Cut along the length center evenly divided into two pieces, and in block A and B and unity Numbers, block length orientation and plate rolling direction. Milling, grinding the surface roughness after treatment for Ra = 1.2 u m - 2.5 u m.

Color: Visual its color is silvery white.

Oxidizing property :In -55 ℃ ~ 200 ℃ - store between three years not metamorphism, no oxidation,

Crack: In the same Numbers of the A and B block with dye penetrant inspection method measured random crack 3 μ m, 3 μ m ~ 5 μ m and more than 5 μ m open crack on one side not less than four, and there are two above width is not more than 3 μ m open crack. Block A and B on the surface crack distribution is similar.
