"In the tin-plated copper alloy terminal material of the present invention, it is desirable that a content percentage of Ni in the Cu-Sn alloy layer be 1 at% or more and 25 at% or less. The content percentage of Ni is set to 1 at% or more for the reason that if it is less than 1 at% the intermetallic compound alloy in which some of Cu in Cu6Sn5 alloy is substituted with Ni cannot be generated and precipitous asperity cannot be formed: it is set to 25 at% or less for the reason that if it exceeds 25 at% shape of the Cu-Sn alloy layer tends to be too minute. There is a case in which the coefficient of kinetic friction is not reduced to 0.3 or less if the Cu-Sn alloy layer is too minute."
"In this case, the Ni content percentage in the Cu-Sn alloy layer is 1 at% or more and 25 at% or less. The Ni content percentage is set to 1 at% or more for the reason that the intermetallic compound alloy in which some of Cu in Cu6Sn5 alloy is substituted with Ni is not generated when it is less than 1 at% and the precipitous asperity is not formed. The Ni content percentage is set to 25 at% or less for the reason that shape of the Cu-Sn alloy layer tends to be too minute when it exceeds 25 at%. If the Cu-Sn alloy layer is too minute, there is a case of the coefficient of kinetic friction cannot be reduced to 0.3 or less."

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

at% signifies atomic percentage, so Cu-27at%Al would have 27% of the atoms in the alloy as Aluminium and 73% of the atoms in the alloy as Copper.
wt% signifies weight percentage, so Cu-27wt%Al would have 27% of the weight of the alloy as Aluminium and 73% of the weight of the alloy as Copper
