If you've always wondered how alloy wheels were made, then check out this interesting tour of the Ray's Engineering factory in Japan. Video after the jump. Aluminium alloys or aluminum alloys are alloys of aluminium, often with copper, zinc, manganese, silicon, or magnesium.
Urea is transported to the kidneys for excretion. A normal range for blood urea nitrogen is generally 8 to 24 mg/dl for adult males and 6 to 21 mg/dl for females. Generally, a high blood urea nitrogen level means that the kidneys are not performing well, particularly if the result is above 50mg/dl.
The normal creatinine level ranges from 0.5 to 1.2 mg/dL, and normal blood urea nitrogen level is between 9 to 20 mg/dL. From the data, we can see that creatinine 11 and urea 200 are both very high. It may indicate that there is something wrong with your kidneys.
