Might be true for one grade of Nd magnets, but there many different compositions and grades, optimized for different applications.
Our motors use what they call UHT (ultra high temp) grade Nd magnets, but even there you find differences.
And BTW, sintering is a way of manufacturing solid bodies. Basically it means "backing a powder together", or something like that.
