Although wear of the measuring surface tips is a key concern, if a scratch was raised on the measuring surface (using a softer surface?) the calibration would be void. Also, fresh metal particles on objects being measured could pressure-weld to a softer steel surface but would not stick to carbide.

The micrometer anvil is a precision flat surface. Any minor irregularity will seriously affect the accuracy of the measurement. Carbide is one material which has high wear resistance to protect the flatness of the anvils even after continuous use

Because it is very wear resistant. A professional quality micrometer is used thousand of times, and this wear would effect the precision.

Carbide is extremely hard. If you are measuring things to the one thousandth of an inch and it starts to erode away you have an inaccurate instrument. The carbide, with its stregnth inhibits erosion.

so it doesn't wear down and render the mic useless. If it is a mic you use daily you would have to have it calibrated at least once a week and replace the tips at least once a month. That would get old really fast.
