Alloy Plate

"Carbon steel plates used to reinforce Grineer armor."

- In-Game Description

Alloy Plate is an uncommon component that can be found on Venus, Sedna, and Ceres. It is usually found in quantities of 10 to 30. Some people have problems acquiring the amounts for certain weapons because of its restricted drop quantity limits.

Gathering Tips
These are based on opinions and may not be true. These should be viewed as advice for finding the materials until better facts are proven.
 * The best place is Kiste, Ceres but the mission is not easy for beginners.
 * Higher drop rate on Venus; the mission with highest drop rate is Venera.
 * High drop rate on Sedna; the mission with the highest drop rate is Tiamat. Kappa Mobile Defense is also good for farming Alloy Plates as well as Rubedo at the same time.
 * Kiliken and Venera are two defense missions on Venus with a high Alloy Plate drop rate. Those missions are useful for farming due to the fact that Venus is a planet easily unlockable.
 * A good boss to farm is The Jackal on Venus, as it drops alloy plates with a relatively higher frequency. It also drops Rhino parts which can be sold for a profit, or used if needed.
