Alpha phase titanium has a hexagonal closed-packed (hcp) crystal structure and exists at room temperature. Although the percentage of patients having allergic reactions related to the use of cobalt-chromium alloys to is very low, one area of concern is the issue of tiny particles (metal ions) that may be released into the body as a result of joint movement.
