Dissolvable Magnesium Alloy Machining Stock

Purchase a material, not a rated completion tool

Dissolvable magnesium machining stock is a material input for a subsequent manufacturing process. Its grade, geometry, processing condition and acceptance tests need to be specified separately from the drawing and service qualification of a finished downhole component.

The Meifu examples below help distinguish those purchase questions. They do not establish that a blank, ball, sleeve or bridge-plug component is qualified for a particular well merely because it uses a familiar material label.

KF-73 grade references

Meifu's OEM-KF73 product page identifies the grade row as KF-73. Its table separates room-temperature mechanical properties from dissolution testing:

The mechanical columns do not specify specimen direction, heat-treatment condition, test method or elongation gauge length. Treat them as attributed catalogue references, not a batch certificate or a high-temperature strength curve.

The dissolution row does not state whether the solution concentration is mass- or volume-based, nor the flow condition, specimen-area method or test duration. Keep those uncertainties with the reference when asking for comparable testing. Do not convert an area-based mass-loss rate into the time needed for a finished component to disappear.

Stock geometry has a separate scope

A separate Meifu dissolvable hollow-bar page lists an inner-diameter menu of 35–80 mm, an outer-diameter menu of 50–180 mm, and a length entry of 1000 mm. The page does not assign that complete menu specifically to KF-73.

Specify the actual inner and outer diameters together, with length, tolerances and machining allowance. Independent menu endpoints are not a guarantee that every combination is manufacturable, available in every grade or held in stock. The ordered material condition should accompany the drawing rather than being inferred from a photograph.

Make supplier offers comparable

These are quotation-stage requirements. They let a buyer use the published material information without pretending that a public table already contains every item in an order's acceptance package.

Keep material and component approval apart

Changing a material grade can affect the proposed part, but a material strength or dissolution entry is not a finished-tool pressure rating, setting-load limit or field-clearance guarantee. If the supplier also offers machining, keep the stock line, machining drawing and component verification responsibilities identifiable.

For the adjacent supply scopes, see drawing-based custom parts and bridge plugs and cement retainers. Send grade, geometry, quantity, destination and the required test package through the RFQ Builder. The manufacturer references establish neither our inventory or distribution rights nor approval of an assembled completion tool.
