Carney funnel measures new standards for metal powder flow rate
A new ASTM international standard for measuring the flow rate of metal powder using a Carney funnel has been developed. The fluidity of the fine metal powder is an important parameter for determining the precise powder loading of the powder in the compact when the powder compact is pressed. The new standard B964 (Carney Funnel Metal Powder Flow Rate Test Method) can be used as a supplement when Standard B213 (Metal Powder Flow Rate Test Method) is not suitable because fine powder cannot pass through the small holes of the Hall funnel. The Carney funnel has twice the diameter of the Hall funnel. The B964 standard has proven to be useful in testing the flowability of fine tungsten powder with excellent precision. The B964 standard is most useful for testing the flow properties of refractory metal powders and iron-based fines.
